My name already is in my sig, cause that way I can pretend people actually know me well enough to remember my name.

I always feel left out when people clearly know each other and are calling each other by their first names, and then I don't know who they're talking about, and people call me just by my sn, but then I really like being on the other side of things and feeling included for a change, so I don't know.
Like Kim said, a lot of people have their name, age, etc. on their profiles... which is how I know that you (TouchVanDerBoom) are really Francesca. And then there's also Kim's approach of signing your name at the end of the post.

A thread for additional background info like family stuff, SI history, etc. *should* be unnecessary because people *should* include the relevent background in their posts, but sometimes I think it would be nice if there were some place for that kind of stuff on our profiles or something since so many people don't include all the necessary background for their posts.
Anyway, I totally understand where you're coming from with wanting easier access to some basic info about people who are asking stuff, but I'm not sure how practical it would really be.
