Making email optional

[Disasterpiece]

Thanks for your reply.

However, if i enter a fake email, I run into problems with a few things.
First I need to try to disable the change email & password field since the user is able to see the fake dummy email adress otherwise.

Next would be to disallow him to use a subscription feature where vbulletin would send emails... And it doesn't seem like there's an option to disable forum email subscriptions for a certain usergroup.

Any way to handle this "cleanly" without breaking too much ?

Like a global hook before sending any emails and prevent that from certain usergroups as well als not displaying the change password/email fields at all?
