I'm just not used to it at all. vBulletin is huge and used all over the net. I expect that I will get used to it in a few weeks, but it's definitely quite the change from the old forum style. I'm not in love with the huge icons next to each post title, but I haven't had a lot of time to look around at things.
I will give it some time and hopefully the guys will listen to some feedback if there are a few things which bug us a lot. Major changes to forums are one of the most difficult things for people to get used to IMO. A simple clean forum is generally a good way to go, but I don't think this gets to far off base.
A very difficult job to do a forum transition... now it's all a bunch of tweaking that can be done if necessary. Good work on the transition for sure!
