As Recommended by Donncha, a very useful plugin for WordPress that generates sitemaps to help Google find your content.
Update: Thanks to the Hairy Lemon, we now have the sitemap being created for Mediawiki, where we host our knowledgebase. Previously , these sitemaps were done by autositemap.com, but the site seems to be on the blink for the last couple of weeks.
Update 2: Thanks to the suggestion of Richard from RedCardinal , we now have the Sociable (bookmarking) and Subscribe to Comments (Email) plugins enabled
