Nothing real happened with this Forum module. OK, was in the release tracker, and.....so what? (It has been couples of times since 2007)...
Sorry, but the bottom line is pretty bad. The forum team would like to have a perfect module. You can test the forum millions of times, but as soon as you release the new version, new problems will came out... and that is ok.
if you'll take another 6 months, (making 2 years since the last update), is even worse than any "regular" expectation. No matter how hard you work, if can not reach your own goal (and looks like Team goals are not release a new version, and maybe no one in the DNN team care about that).
Do not say that the more you test the better the forum module... (so far, the more you test there is NO better module, because the module does not exist in the real world)...
having under DotNetNuke site this forum module is something pretty bad for the community, "I feel in the past", far far away from the "WEB 2.0",. You have thousands of users but just couple of them are posting in this forum/section (did you figure out why?).
CU later...
