Feature to 'resend' validation email

I would also like this feature. It seems that I have just been told that our SMTP server wasn't working for the last 3 months, and there have been a lot of unverified registration attempts. So, instead of emailing everyone individually to get them to go through the password recovery process, it would be much easier if I could select all the unverified users and click on a 'Resend Verification Email' button.

Obviously, if this feature isn't already implemented, then I will have to do it manually, but others in the future would certainly benefit.

Even just an ability to email users from a specific group(s) would be of great help...
