What Forum software is Kayako using?

Kayako uses forum software at http://forums.kayako.com, but I'm unsure what software they're using there. I like it and would like to see what is powering it. (Invision Power Board, vBulletin, phpBB, etc).

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.
