The Message Inbox rules! But i still use the textarea at the bottom of my homenode for composing long messages, so more than one line can be seen at once. How about using a textarea in the Message Inbox?

The only problem i can see is that textarea doesn't have a maxlength attribute and so allows you to enter more than the 255 chr limit, so long messages truncate. But this could be addressed by counting the chrs in a submitted message, and returning the textarea with the truncated text so it can be resent.
