I think others may have missed this topic, I've only noticed it today
We probably already came to a decision to not go with this idea, although Hylis seemed to support it. I think it would be a good idea to offer some sort of subscription to become a premium member along with the donation target. So current subscriptions give each month the little boost it needs to show people are supporting the project each month therefore encouraging one-off donors to contribute something
For the rewards the possibilities are endless of what we could offer premium members, such as personal statistics showing what are their most successful maps are etc.
-Reset it monthly, but if there are any subscribers -> add that amount at the start of each month
