I posted a review of threads in this month's ezine. It's a nice forum software, but still in it's infancy regarding maturity. V6 goes a long ways to helping this, but it still has some work to do.
Once V6.0 is out and the bugs are worked out, I'd look to see it improving quite rapidly, scream is good and getting the coding worked out for the major changes introduced this time around provides a very nice basis for future improvements. I plan to put together a "ubb-like" interface with the templates if that's what your users are used to, there's lots more in store I am sure
