Thread:Extension talk:Invision Power Board Authentication/I find this extension confusing

Whlie both IPB and MediaWiki are written in PHP and use a MySQL database, they are not under the same license. MediaWiki, like phpBB and myBB, is under GPL, while IPB proprietry. Although IPB and vBulliteen both appear to have similar core features to phpBB, there don't seem to be any wiki packages that match MediaWiki in the same way.
