Yes, that does make sense and I have seen that, but not tried it, thanks MMario.
The thing I'd like to be able to do is say, for instance, call up all of the PM's I've received or sent to one particular member and delete them all at once, without having to tic every one of them. If I can't do that, it's okay, it's just going to take a long time to sort through them all otherwise:-)
