Default Secondary Usergroups by default on signup

[woostar]

Does anyone know how I would go about gving new members default secondary usergroups when they signup (without having to use promotions).


I'm guessing I would use hook:
register_addmember_process

and something like:

PHP Code:

$userdata->set('membergroupids', '20,21,22'); 


Does anyone 'in the know' if I'm looking in the right area?


Thanks

Yep, that should be correct.
