You could hook up your plugin to "user_register_completed" and them add in their account some credit, it should be easy
Well, I also think it should be easy. I've been trying to make changes at the wallet.php and functions.php files, but it didn't work.
What I need is quite simple (when one knows the complete how-to, and I miss a few steps...). In short: all I need is just a way to, when a new user registers itself, he automatically and instantly get's a certain amount of credits (defined by admin) in his account.
This feature exists already at least in 2 other plugins (Paypal Advanced and Ultimate Payments). I Think it's time for the official payment plugin from Osclass give us the same possibility.
