So this is an idea that I stole from the Korean side of the internet. They call it 100일 달성표 (100-day achievement chart), but it doesn't have to be done in 100 days.
1) Creator makes a 10x10 grid. Each box is numbered, from 1 to 100.
2) Every time Creator completes a task relating to their goal (e.g. a comic page), they fill out one box, starting from box #1.
3) Anyone who wishes to support Creator can claim a number. Let's say you claim #10. (Some Creators may wish to keep it between friends though, so ask before claiming!)
4) When Creator has completed 10 tasks and reaches box #10, then you have to give them a gift -- e.g. a sketch of their character.
This is mine:
Normally I'm uncomfortable receiving fanart for ANY reason other than "I love your character," but here, I feel okay since I'll be earning it.
If you decide to make your own grid, post it here! I can't make any promises to claim a number for everyone, but considering the community, I'm sure no gridder will go without a supporter or two, if not more!
