Custom E-mail System

[itsRahul]

Hi guys, I was advised to make a thread here regarding the issue I originally put in a support ticket. Anyway, I wanted my forum to require people to use a specific e-mail address at registration. In other words, if I wanted to specify "yahoo.com", then people could only register with "whatever@yahoo.com", and if they put in an invalid e-mail, it should not go through with the registration.


Can anyone help guide me through the process that is needed to have this done? I'm not fluent in code, but I have worked with a lot over the last year so I'm not clueless either. I will probably understand if you put up code but if anyone can help me, please do; perhaps step by step (I was told that this would require custom plugins, queries, or template modifications) directions would be ideal.

Thanks in advance.
