Force Users To Update e-mail address

[webspider]

I'd really like a way to flag / lock a users account and force them to update their email address before they can access the board. Does anyone know of a hack for this or could a coder make one?

Um, just move them to usergroup 3 (e-mail confirmation group).

Yeah but it would be nice to have it done automaically. I'm trying to install vbouncer now. Looks like it will do the trick.
