Unlike MS Paint, when I use the text function to type in text onto a picture, I can't seem to be able to move the text box, despite the outline that shows for it. Is there a way I can re-position text that I type without having to type it again?

There's a move button. Go all the way over to the far right, down one, and over one.

Yeah, I figured all of that out after a few minutes after posting this, as I was still messing with GIMP, but I didn't want to make myself look sillier than I already did. :P Thanks for your help, though. ^_^
