JP, glad you're here. As someone who spends as much time on TFF as I do here, here's my thoughts.
No animated smileys. Sometimes I open a page on TFF, and all the animated smileys are distracting. Some things are best relayed through words, and not an animated gif. I do wish the add pic from hard drive had been added to the ckeditor toolbar. That was my favorite feature of 7.5.8. We've lost legacy pics when the photo hosting accounts were dropped by the original posters.
I really like the current layout of the PB forum, and I hope that never changes. The recent posts table/div could maybe be expanded by 5 posts. Some posts roll off pretty quick some days, and would be missed if users don't check the recent posts.
One thing I hope PB never gets is the wall of shame. Most of us are virtual or real friends, and this forum is moderator driven, so I think posting issues are best handled privately. I know that's not possible on TFF, but I sure like it here. If somebody gets put in timeout, I don't want to know about it.
Having said all that, all your forums are absolutely rock solid, and I'm so happy you and Bob are friends and partners. I've quit posting on some Yuku boards because of their flakiness. UBB is by far the best.
