374	<p><strong>1. What this plugin does</strong></p>
375	It shows excerpts of the latest comments and/or trackbacks in your sidebar. You
376	have comprehensive control about their appearance. This ranges from the number
377	of comments, the length of the excerpts up to the html layout. You can let the
378	plugin order the comments by the corresponding post, or simply order them by
379	date. The plugin can (optionally) separate the trackbacks/pingbacks from the
380	comments. It can ignore comments to certain categories, and it offers support
381	for gravatars. It only gives extra work to the database, when actually a new
382	comment arrived. And you can filter out unwanted pingbacks, which originate
383	from your own blog. And it is a widget.
384
385	<p><strong>2. Installation</strong></p>
386	Since you are reading this text, you already uploaded and activated the plugin.
387	Now you want to add the plugin to your theme. There are two options to do this:
388
389	<p><strong>2.1 Modern Theme with widget support</strong></p>
390	The plugin is a <a href="http://automattic.com/code/widgets/">widget</a>. If
391	your theme supports widgets, and you have installed the widget plugin, adding
392	the plugin to the sidebar is easy: Go to the <a href="themes.php">presentation menu</a> and drag
393	and drop the widget into the sidebar. Don't forget the Get Recent Trackbacks
394	box. And you might want to change the title. All done.

420	<p><strong>3. Customizing</strong></p>
421	The strongest feature of the plugin is that you can change the html layout in the admin interface, by filling in templates. In the templates you make use of macros, that are later replaced by the actual data.
422
423	<p><strong>3.1 Using the Macros</strong></p>
424	<table>
425	<tr><td valign="top" nowrap>%comment_excerpt</td><td>The text of the comment. It might get shorted to the number of characters you entered in <em>"Long comments are chopped off at..."</em></td></tr>
426	<tr><td valign="top" nowrap>%comment_link</td><td>The URL to the cited comment.</td></tr>
427	<tr><td valign="top" nowrap>%comment_author</td><td>The name, the commenter entered in the comment form. If she left the field empty, the name is "Anonymous".</td></tr>
428	<tr><td valign="top" nowrap>%comment_date</td><td>The date, when the comment was posted in the style you configured as <a href="options-general.php">default date format</a>.</td></tr>
429	<tr><td valign="top" nowrap>%comment_time</td><td>The time, when the comment was posted</td></tr>
430	<tr><td valign="top" nowrap>%time_since</td><td>Time since the comment was posted. For example: "9 hours 16 minutes".</td></tr>
431	<tr><td valign="top" nowrap>%comment_type</td><td>"Comment", "Trackback" or "Pingback".</td></tr>
432	<tr><td valign="top" nowrap>%gravatar</td><td>This macro becomes a complete image tag. If the comment author registered a gravatar with <a href="http://www.gravatar.com">gravatar.com</a>. Example:<br /><img src="http://www.gravatar.com/avatar.php?gravatar_id=1ebbd34d4e45cac&size=25&rating=X"/> </td></tr>
433	<tr><td valign="top" nowrap>%gravatar_url</td><td>This macro becomes only the URL to the gravatar. Example:<br />http://www.gravatar.com/avatar.php?gravatar_id=1ebbd34d4e45cac&size=25&rating=X</td></tr>
434	<tr><td valign="top" nowrap>%profile_picture</td><td>Becomes to URL of a profile picture. Use it like this: <img src="%profile_picture" width=16 height=16>. This only works after activation of <a href="http://geekgrl.net">Hannah Gray's</a> <a href="http://geekgrl.net/2007/01/02/profile-pics-plugin-release/">Profile Pics Plugin</a>.</td></tr>
435	<tr><td valign="top" nowrap>%userid</td><td>If the comment author is registered with your wordpress, and was logged in, when she wrote the comment this is replaced with the user id, she has in WordPress. The user id's are listed here: <a href="users.php">users.php</a>. You can do fancyful things with this macro. For example you may construct an image url, that points to pictures of all the authors of your blog: <img src="/images/user%userid.jpg"></td></tr>
436	<tr><td valign="top" nowrap>%author_url</td><td>The URL, the comment author left in the comment form, or if the comment is a trackback, the URL of the site that issued the trackback.</td></tr>
437	<tr><td valign="top" nowrap>%author_url_href</td><td>The same like %author_url but inside a href statement. If there is no URL, the whole macro is empty. Without a href="" statement the link looks like a link, but is inactive. Use it like this: <a %author_url_href title="%comment_date">comment_author</a></td></tr>
438	<tr><td valign="top" nowrap>%post_title</td><td>The title of the posting that was commented.</td></tr>
439	<tr><td valign="top" nowrap>%post_link</td><td>The URL of the posting that was commented.</td></tr>
440	<tr><td valign="top" nowrap>%post_date</td><td>The date when the commented posting was published.</td></tr>
441	<tr><td valign="top" nowrap>%post_counter</td><td>The number of comments this post has..</td></tr>
442	<tr><td valign="top" nowrap>%trackback_title</td><td>Only applicable in trackbacks: The title of the trackback. It might get shorted to the number of characters you entered in <em>"Long trackbacks are chopped off at..."</em></td></tr>
443	</table>
444
445	<p><strong>3.2 Group by comments</strong></p>
446
447	If you want to order the comments by their posting, you will have not one but
448	three templates. The middle one is just the same as in the normal order. The
449	first and the last template are used to generate headers for the grouped
450	comments. Usually you will show the %post_title in this header. This is the
451	html markup that is generated by the templates:
452
453	<style type="text/css">
454	<!--
455	.top-example { vertical-align:top; }

532	<p><strong>4. Miscellaneous</strong></p>
533	<ul>
534	<li>Don't worry if you screwed up the template, reset the template to default and try again.</li>
535	<li><em>"Wrap long words at..."</em> means: words, that exceed this length are split into fragments to prevent damage to the layout of your blog.</li>
536	<li>"<em>Ignore trackbacks originating from this ip address</em>" on the
537	configuration page for recent trackbacks is useful for filtering out pingbacks
538	that occur when you have a link to your own site in a post.</li>
539	<li>If you select to exclude comments made by blog authors (your own comments) from the list, then the comments which you made, when you were logged in, are ignored. If you also want to exclude comments you made, when you were not logged in, you can select to also consider the username and e-mail address.</li>
