Anyway, here goes. I know this has been talked about a lot and I do agree that mandatory signing of antipoints isn't a good idea. However, I do know that a lot of members (myself included) sign their APs. Now, I've seen the signing thing misused simply by typing someone else's name/nick in there. My suggestion is that there be a checkbox in the AP correction window that says "Sign this assignment" or something similar to prevent abuse. I know a few people (myself included again) who've got negs from someone pretending to be someone else, therefore this idea.
Cheers,
