I was wondering if there was a setting to block certain domain names on the email field. For example, free email domains like: gmail, hotmail, yahoo, etc.
Maybe there is something I can place in the additional settings box, or tack something onto the tag generator? I feel like the additional settings could have some great potential, sadly there seems to be no documentation on it.
If there's nothing built-in that I can use, I'll just end up editing the PHP myself.
