Hello,
i have come to this thread after having being pointed by an user asking for this feature and wanting to show me the amount of people asking for this.
I have just completed the release of CM2F Groups 1.0 PReview, and i am hunting for new features to be included.
One that has been implemented is, the Forum2Forum feature where you can bridge 2 forums together.
The other one that i am working on is to finish the port to Vbulletin and Xoops NewBB. This task is taking more time, because of the complexity. I have been able to have the integration, but it is still making errors, and the admin interface is being hard to port.
So i will start to look into MediaWiki and see what could come out...
Regards, D.
