Registration should be automatic and not manual

I get complaints from my users about not being able to register on the forum for 5 days! I cannot afford to irritate people in this way.

Here is the email I got:
"I tried to register at the forum and nothing works.
I even wrote to the rep. and he told me that they approve applications manually one by one.
He has yet to give me a confirmation link and that's now at least five days since i've been trying to register.

What a hassle!"

I advised to use OpenID which is much less hassle.
But this is simply wrong, please do something about this. Thanks!
