Qt centre forum.

Hello Qt centre staff,

I'm enjoying Qt forum. I think it's very well made.
I'd llike to implement my own community forum.

Are the Qt centre's forum sources available ?
Do you sell them ?

Our forum is based on vBulletin - it's a commercial product that you have to buy. We find it a very good piece of software and we are very happy we chose it for our codebase (although we had to pay for it).
