Just curious about how this would be different from the ECF Wiki. If the main purpose is to have someplace which functions as an information repository, where things are easy to find, it seems a Wiki serves that very well. Granted, it's easier for forum members to just post threads, since there isn't any new Wiki markup to learn, and organizationally, a forum is a bit more loose than a Wiki, so it's mostly easier to find where to put whatever. But there's already a Wiki here. I've only just looked around a bit at it. I suppose one issue is that Wikipedia and vBulletin don't share login info. Not sure how tough it'd be to somehow hack that into place, as I haven't looked under the hood at either package. Probably a PITA. But then, depending on which CMS package you've chosen, doesn't the same issue exist? Or is there a CMS designed off-the-shelf to work with vBulletin?
Either way, I think this a good direction to go -- I mean having something like a vaping encyclopedia, or whatever you want to call it.
