I think that the forums should be merged. Like other people have said, take the best of both sites and make a PKI mega-site. I personally like PKIU's layout, and PKIC's pics and updates. As a longtime PKIU member, I would like to see it happen.
But in order for that to happen, we need to reach a common ground. Not just with the layout and content of the site, but with the members as well. I've been at PKIU for a long time (at least is seems like a long time) and i've seen it alot of changes, but I think it's time for another change. It's going to be a more drastic and controversial change, but in the long run, I believe it will pay off. Once and if most people can settle their differences and show some respect for others, it will be better than either site ever was, or ever could be on their own. I know everyone learned these things in first grade, but some people forget that a little respect and courtesy goes a long way with others.
(Not intending to offend anyone, I'm just trying to make a point)
