in phpbb, you have the ability to take back pm's if they are still unread by the recipient. could vb do this? it's a pretty handy feature, although on the other hand it might increase outgoing mail... dunno, it's just an idea.

sent something you'll regret?

no, but allowing people to take back their sent-but-unread pm's, they could add more text to them without having to pm-bomb the person...
