Yikes, I'm going to have to read some of the fine print of this upgrade a little closer.
I'm seeing two things that I'm not sure I like--either I have missed it in setting things up, or they've gone away.
First, I like being "invisible" when I'm online--especially on my board; it's just the way I am. In addition, the main attraction to my slice of cyberspace, Nora Roberts, needs to have that anonymity, too.
So, am I missing something there?
As long as you have not selected to prevent invisible members under general in the CP, all members can select if they wish to be invisible.
Second, I also liked the ability to set up how the forums appeared for me. Example, here @ UBB Central, I have the left side of the portal page turned off when I'm looking at the threads/messages.
At my site, I turn off both sides when I'm viewing the actual board.
Again this is a user selectable option as long as you have not blocked it within the settings.
