I guess I'll want hard thing to do, how I reset all users' password by using Guid, or Random (differenet from the others' passwords) after than, I want to email their new password.

They'll use new generated pass or if they want they can change again ?

The cause is that, many users send me an e-mail, they want to reset them pass.

This thing will be perfect :)

One more advantage is, I am sure there is a lot of users have already forgetten their passwords. Also they can start post again :)

Thanks.
