Please enable BBCode and "\n" parsing in member descriptions, and if possible increase the size a bit beyond the 200 character limit.
Also, if possible move the description field further down in the client close to the other user-controlled area (the avatar).

This would enable people to further personalize their profiles in a controlled manner, and enable devs to use this field in more ways than it was originally designed for, since it can already be set via server query.
