Working on it at http://tangledbranch.com
Still a major work in progress. I'm working on a visual editor for the forums that's WYSIWYG - if you look, don't go by the aesthetics.
I'm hacking the hell out of Wordpress: Private groups, group forums, friends, will try and get in realtime chat... It's ugly right now, but taking shape.
As far as roles go for the there are
The forum has a whole set of additional roles not tied to these:
I have all the security in place, the back up functionality and all the gooey bits. Now I'm trying to make it at least presentable and useable.
Again if you look, please ignore the colors, the layout and all the aesthetics. I'm working the guts. I'll likely be in the code a lot, so sign up at your own risk and if you see it flip back and forth between appearances. It's just me messing around.
I feel bad about just picking a name, but if it's any consolation - I haven't slept yet.
This is not ready to start using, but I hope for it to be, for at least us. Tonight.
