I've been around here previously, but I was curious about what goes on on this site...Thanks...
Howdy and welcome back.
Just hanging out and chatting mostly. We have the usual assortment - some hang out to chat, some hang out because we are bored, a couple hang around to find fault with others so they can feel more righteous, a couple just make comments to provoke reactions.
(I might possibly have played three out of four of those roles at some point...)
Just keep in mind with every comment (especially any comments of mine!) that it's just words on a screen, made by people you will probably never meet, people who don't really know beans about you. If the conversation gets too personal, keep in mind that none of us really know anything about you, so we probably don't know what we're talking about.
