EDIT: I have now changed to charge up front. Again, those who are already patrons should not see any change. Please let me know if you experience any issues!
Since the introduction of nsfw requests, I've had instances of people pledging and then retracting their pledge to view the locked posts without payment. Due to this I will be changing to "Charge up front"
What this means for new patrons: Exactly what it means. To view any content you will be billed at the time of first becoming a patron. From that point on you will be charged on the 1st of every month. Due to this, if you would like to become a patron, I'd recommend becoming one in the beginning of the month to avoid having to say, pay $5 on the 28th, only be charged another $5 on the 1st of the next month.
What this means for current patrons: If you've already had a payment processed, then it should stay as the monthly payment. However, if you edit your pledge to that of a higher tier before the first of the month, you will be charged the difference on the day that you change it. Also, if you change your pledge to a lower tier, you will not be refunded, due to already accessing content that was available on the higher tier.
I had wanted to avoid doing this to give my patrons a little breathing room when it came to payment, but I'm not up for people accessing locked content without payment. I will be changing it to charge up front in the next few days.
