I've been thinking on this idea for my patreon.My sketch tier is currently closed to a maximum of 15 people.I'm thinking of making that number unlimited, but with the condition that you won't have a %100 guarantee of having it done that monthThis means that the current sistem of stacking will be gone (it's still be applied for the people who didn't used em yet)Also that would mean making a tier between $5 and $10What do you think?
