Yep, I know Mike owned Nation before selling it off, then started Army a few years later. Vertical scope owns both above and really don't put alot of energy into them. That's what I hope will be different here with PSA, as I am not a employ just watching over the site, I'm the owner.
FB did take away alot of members, but forums are still alive and well. I have seen several forums start from 0 posts and have become very active, so people still like using forums. We all know FB is horrible with keep content to search for and that's where forums excel. Also, to me forums to me feel more like a community then FB groups.
