I moderate at several forums, and making it easier to move threads is something at the top of my wish list. Basically, part of a moderators role is to make sure that members place the right threads in the right forums. Shawn at DigitalPoint used the AJAX support in vB 3.5 to increase moderation efficiencies. For demonstration purposes, I have made a quick MPG video of me dragging a thread in the Google forum to the Domain Names Forum.
A cool new feature from a cool SEM forum. Probably only interesting towards administrators and moderators, but cool stuff nevertheless.
