I don't know C well, though I have a basic understanding of programming languages in general. A quick question.... How hard would it be to make it so that User-Agent doesn't show up in the edit buffer (when $edit_headers is set, and so that Mail-Followup-To does show up? I'm imagining this should be a pretty easy change, but after taking a quick look, it wasn't immediately obvious which code I'd want to muck around with. I'm guessing compose.c? w
