I tried to find in the forum a similar question but unfortunately I could not. So, this is the scenario:
I have a list of emails. When a new user tries to register to my site using the cb registration form and when he presses the register button, I would like to run a custom code in php which would check if his email is in my list and then do some things.
What I really want to know is where I can find the code that is running when a new user clicks the register button in the registration form? I could embed there my custom code!
