...and I just commented on Crispy's spelling errors!
Oh well.
As for the Bio, just post up what you have and leave a footnote at the bottom, letting everyone know its still in progress.
As for bringing a friend along, thats great! the more the merrier! ;)
...and as for loving me...well, you won't hear me protest. :P
Seriously though, don't stress about the Bio's. I probably shouldn't tell you this but hell even if you just put your character's name up , you're ahead of me...its been like 4 or 5 years and I still haven't done one yet for any of my characters.
