Also, I'd like to add my suggestion:

Remove e-mail field, it serves absolutely no purpose.

Place a checkbox for sage field. Make all sage be silent. That is, no announcement at all. The only way for someone can tell it was a sage post was because it didn't bump the thread.

This is a feature I use on my text board software, which it inherited from Hotaru's original TinyBB.

Seriously, the solution is so easy, I cannot believe people have stuck to the standard model for so long.
