Yes, I guess that would seem cool! Maybe it could be still usable by every one, even if they don't have a facebook account?
I was thinking something along the lines of a box like the one where we all use to make posts. If there were more you wanted to add about yourself (that doesn't seem to fit in the About Me page or that might make it overly cluttered), you could put it there like a little notepad (nothing huge or over-the-top).
For example, my user name has a special meaning. I could put that sort of stuff over there, but it could be separate from the Visitor Messages Wall.
Ah... I hope I'm making sense.... ~lol~ I'm just glad I was able to post something that didn't seem to get on anybody's nerves! (Being a newb is hard. xD) Thank you for your time!
