adding [wiki] links from SMF to MediaWiki?

[dcltdw]

Hi, everyone!

Does anyone know of an extension that allows a SMF user to use something like
  [wiki]SomeWikiPage[/wiki]
?

Right now, my users can do [url src=http://www.TheAttachedWiki.com/SomeWikiPage[/url], but it'd be nicer if there were an alias I could set up inside SMF.

Thanks in advance for any guidance.

There is a mod that allows custom BB Code...
