Something very special happend with this module.
Every 12 months or so, a new version come out (or longer), so people start to complain about that. The last version was release on October 16th 2007 (was a big jump from 3.x to 4.x). When Users started to moving out to Active Forums (Which is great) the Forum TEAM 'show' a new version...so, the team keep the users quite happy for a while (one or two months), until they figure out that the project looks like a dead project. The truth is you CAN NOT help them because they DONT NEED extra help (they simply don't accept you time, it is a ultra close team)
So, nothing to do with that... You need to decide to wait 'forever' (and dont ask for a new version, or fix ultra common and painful bugs) or move out as soon as possible to another forum module.
I am NOT agree how DNN release they module versions. The release tracker only make stuff harder. Many open sources have a stable version and dev version....so, why dnn won't take taht way? (it is faster to develop and improve modules and applications)
The why DNN release the modules is closer to Microsoft way than OpenSource way....
Cheers,
