New SignUp Listener
Jamroom Developers
If you look in the jrUser module's _init() function you'll see the events it fires. The ones you're probably interested in are:
// register our triggers
jrCore_register_event_trigger('jrUser', 'signup_validate', 'Fired when a user submits account data for a new account');
jrCore_register_event_trigger('jrUser', 'signup_created', 'Fired when a user successfully signs up for a new account');
jrCore_register_event_trigger('jrUser', 'signup_activated', 'Fired when a user successfully validates their account');
jrCore_register_event_trigger('jrUser', 'login_success', 'Fired when a user successfully logs in');
......
Pick one of those that suits where you want to interact with the flow and define a listener in your module, then when the event fires you can do your stuff.
