with S2member

Hello,
reading this conversation http://www.s2member.com/forums/topic/mismatched-paypal-and-registration-emails/, it seems that there may be problems with S2member interaction and Paypal if BBQ is activated.

They give this tip Otherwise, you may want to find the add_action() hooks for the plugin and add a conditional such as:

if($_GET['s2member_paypal_notify'] !== NULL) { # If s2member_paypal_notify is not set / is not the PayPal IPN response URL
	# Hooks and filters
}

but I’m not sure how to use this.
If you got an idea…
