Well, at this point, it's clear I'm not getting to a wholesale rewrite of WFG any time soon. Or maybe ever. So, instead, I'll spend some time doing WordPress upgrades over the coming few weeks. Looks like there are some plugins for bbpress that provide private messaging, for instance. I've got some tight deadlines at work, right now, so I can't promise dates, but I'll do my level best to get to them by the end of the year, and hopefully by the end of the month.
If you guys have a short list of changes you'd like to see, respond here with your suggestions. Again, no promises, but I'll try to do at least a few of them.
