RCR, I've never heard of that one and I've been on various crafty and photography forums for like 15 years now. The most common ones are Invision Power Board or IPB and phpBB. Those you can get free skins and themes...and by that, I just mean custom color combos and such, although my favorite board used to have themes for all seasons and there was one we could pick that was sandy colored like a beach and had tropical plants around the edges. It was so pretty and easy on the eyes. The owner there had a theme like yours to match everything for the general public just coming in, but once you were in, then you could have your own look to see when you logged in. It was great fun for all of us when they released new freebies for us. We had like 15 to choose from.
Speaking of that forum, we had it so that nobody could see any posts unless they were registered. It felt a lot safer to post personal info. I worry here that we have a lot of personal info out there and it seems like it would be easy enough to stumble on to someone you know if you were suspicious of anything. Would it ever be possible to require logging in before the forum could be read?
