Getting pings on your domain name

Adam asked how I did this and I couldn't find my notes, so here they are...

1) In Categories, set up a category to catch the pings to your domain. Turn on "accept incoming pings".

2) Add this to your main index:
<!--
<rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
xmlns:trackback="http://madskills.com/public/xml/rss/module/trackback/"
xmlns:dc="http://purl.org/dc/elements/1.1/">
<rdf:Description
rdf:about="<$MTBlogURL$>"
trackback:ping="<$MTCategoryTrackbackLink category="CATEGORY_NAME_FROM_ABOVE"$>"
dc:title="ping <$MTBlogName$>!!"
dc:description="<$MTBlogDescription>"
dc:identifier="<$MTBlogURL$>"
dc:date="<$MTDate format="%Y-%m-%dT%H:%M:%S"$><$MTBlogTimezone$>" />
</rdf:RDF>
-->

3) Rebuild your index page.

When someone links to your index, you'll receive a trackback ping (unless your spam blocking plugin that grabs it).

(Now without smiley faces!)
