When you go into your User CP / Edit Profile area, the input field for the "biography" is a single-line text box - should (could?) it not be a multi-line text box so it's more readily edited?

Currently if you hit enter whilst in that field then it submits the form, and you can't copy/paste multi-line text in either.

Or is it intended to be a single, brief sentence rather than a collection of bullet points?
