Payment change (Patreon)

I change to subscription-based. This means instead of getting charged on the date 1st each month, your next charge will be on the date you join. Beforehand, every patron gets charged on the 1st of the month. This avoid new people to get double charged if they joined at the end of the past month.

This only affects people who join after this post. For those who already join, nothing is changed.
