Hello, paypal mails are poor in information about who has paid for a subscription. With this small modification you´ll know (with permission of paypal, they don´t send allways all the information possible) the username and the userid of the paid subscriber.

In subscription_payment_paypal template, find:

<input type="hidden" name="item_name" value="$subinfo[title] Subscription" />


change with:

<input type="hidden" name="item_name" value="$subinfo[title] Subscription of $userinfo[username] ($userinfo[userid])" />


Regards
