Thank you for the reply. the only thing left is that I am making a froum for a university staff and their email addresses are like this:
@hf.uio.com, @ili.uio.com, @mat.uio.com and so on... Your reply solves my first questions. but regarding this type of emails, how should I change the code? Thanks again.

Either you define all the allowed subdomains:

return preg_match('/^(([^<>()[\]\\.,;:\s@"\']+(\.[^<>()[\]\\.,;:\s@"\']+)*)|("[^"\']+"))@(hf|ili|mat)\.uio\.com$/', $email);

Or you just allow everyone from uio.com to register:

return preg_match('/^(([^<>()[\]\\.,;:\s@"\']+(\.[^<>()[\]\\.,;:\s@"\']+)*)|("[^"\']+"))@(.+\.|)uio\.com$/', $email);

(You should test that code before you use it, I just copied Nibbler's example and changed the domain.)

Hey,

I was wondering if there was a way to enable avatars, but not permit normal users to upload or change them. I didn't find any option for this on the "edit group" page, so I thought I'd ask here.
