Subscription Billing Info (Patreon)

I was made aware that the subscription billing only works for new patrons or patrons who cancel their subscription and re-pledge.
If you were a patron before I made the change (I think it was on the 29th of September), you'll get charged everytime around the 1st of the next month as usual as long as you keep your pledge and don't re-pledge.
I'm not sure but I think if you cancel your pledge and immediatly repledge just to change to the subscription model you may get charged immediatly, just as a warning.
