Some changes to the page (Patreon)

Hey folks! Just wanted to give you all a heads up on a couple of changes.

Firstly, I'm changing from first of the month billing to subscription billing, which means that any new patrons who join after now will be billed each month on the date they subscribed.

This will free me from the pressure of trying to schedule releases around the beginning of the month and instead allow me to release completed animations simply when they're done. It's also more straight forward for subscribers, and will prevent people from getting double charged on the first if they subscribe near the end of the month.

I'm also now offering annual subscriptions for those who might want them, which gives subscribers a year of access for 15% off.
