This is exactly what I had suggested about 6 months ago, was not sure if this was possible, but thought it would be the perfect thing. Thanks heaps!
When your forums become large, you get so many people who think they can register with a fake email address eg.
123@fake.com and then some of them will contact you, saying they accidently typed in the wrong email address, others will probably sign up again, or just give up.
Just one question tho what happens if the mail server is temporary down?
