Alrighty, how about the full screen ads? They don't seem to work in any browser I have tried. I have viewed them with Netscape 4, IE 5, IE 6, and Phoenix on a variety of computers. Some users seem to have problems with them infinitely looping as well.
Overall though, you are correct. The forum does work pretty good, and is relatively bug free. However, the experience is a little offputting for a lot of people as FuseTalk doesn't allow for a lot of things that PHPBB allows, and isn't quite as refined. I realize that it's easier on the bandwidth and all though, so don't get me wrong. I definately support your using it, and I am not demanding that you use PHPBB, I am just saying that it's not as featured as I would like, and it continually does strange things for me.
The main reason for my buggy comment though has been the server. It's been well behaved since you have taken the new memory out of it, but it was driving me nuts for a few days.
I would try to post, but it wouldn't upload the post, so I would hit post again... it would then give me an error, so I would click back on the thread a few times until it worked, copy and paste my new post into the reply box, and try again. After a couple of repeats it would work, but you have to understand my annoyance with the "feature".
