Also I have been donating 2.00 USD a month for years on my Paypal account. Is that run by Patreon?
No, Patreon is separate system. Before Patreon, PayPal donations was the only option. I prefer people use Patreon, as it:
a) Is public, so people know how much I'm getting
b) It has easy mechanism in place to provide content or other stuff to supporters.
I still accept PayPal of course, but I'd prefer if people switched to Patreon. But no worries if you don't want to though.
