You realise that you can just hit the edit button once it has returned to the main screen and check then edit your post? Or you could just scroll up and check it before you post(I know that would be of no help with pics.)

Matt, I guess I just never saw an issue with the posting box...to me its just a work area. With my lousy typing skills I'm usually looking at the keyboard anyway

As far as an underline option, this normally signifies a link, so random underlines can get a bit confusing. Bold & italics should handle any word(s) that need special attention.
