How do I delete all users in a user group?

[mtbrider]

Hi, I have about 360 users in the "Users Awaiting Email Confirmation" user group, most are spammers who did not complete registration. I'd like to delete them but I can find a way to do it en mass. Ie- Delete all the users at once as opposed to having to do it one at a time (very time consuming for 360!).

Can I delete them all at once? If so, how?

Regards

Steve
