By the way, for anyone reading this, as an experienced wiki admin, the hardest part, at least for me, of maintaining a wiki, is maintaining interest and involvement with the wiki. People need to use it regularly to care enough about it to be willing to update it.
I think the key in this is making people actually
use the wiki, which they won't necessarily do if it's just a link at the top of the page. OTOH, an addon like the following could help a lot:

When people see hyperlinks in posts to wiki pages, they will start caring more about the wiki pages and will want to contribute. Hence, if you add a wiki, you might want to add a keyword to link replacer as well.
Just an idea...
