So cool. Almost everything that you can think about someone has already developed for the MediaWiki. The MediaWiki is so incredibly powerful.
The lastest thing that we added to the The Pet Wiki has been a way to comments on pages. After adding the extension for the comments, you need to add <comments/> to the Wikitext of the page. That creates a link on the page that encourages people to leave comments on the discussion pages. We’ve added it to the Great Dane and Border Collie pages. It would be really cool if we could automatically update on all pages, but beggars can’t be choosers. Maybe they’ll have that in version 2.0. 🙂
