if one tries to rename an inbox, citadel should refuse it, and make a popup jump into the users face, (if he's using imap a page maybe?) and direct him to the way to create a public room with mail inbound allowed..
one problem is that the page couldn't be localized if it comes from within citadel, right?
but better that way, then making something the user doesn't want. (killing the users inbox) but rather have a public room, wher mail can be delivered from outside in.
