I have absolutely zero experience with Expression Engine but I've been given a task to fix a validation on a registration form. There's a username field that is supposed to validate as email address only but right now it accepts any string. I have no idea if that registration is a plugin or built in. I found it's template in /themes/forum_themes/site/forum_member
I suspect I need to find a model for the registration db table now and change the validation type from string to email? Or something like that? I have basically no idea where to start without getting to know EE from scratch.
Any help apprieciated. Thanks
