To add onto what Gaz and David are saying, as far as I know, there's this little thing called "or a usergroup" and everyone can see it when making PM's. Why am I bringing this up? Simple. When making your test promo, and you need to send it to all admins but can't remember who all they are, go in that box and select "administrators" Then, low and behold, the admins will all magically get your PM. That way there's no accusations of users being lazy, forgetful, or admins feeling like they're left out.
