bbPress.org

@Trent and everyone, this plugin intercept login process, if the logging user hasn’t activated the account, then it will be redirect to bb-activate.php. After successful activation, the user will be redirect to bb-login.php.

And when new user is registering, this plugin doesn’t interfere the normal registering process but add an additional usermeta and send the activation code right after bbPress send the password mail.

So, there is no way this plugin will break the password being sent.

Edit: Currently, user gets TWO mails after registration, one is for password, another is for activation code. I am not planning to merge them into one, because that would have to touch many things and I don’t like that.

Edit: I knew there are some topics about mail problem, but I can’t find them now.
