My instance of ~300 users (and uh, far less active ones) is costing me $223/year
I’ve had users donate about $25 so ~10% community funded and 90% admin funded.
That’s fine by me at the current cost. Though if we somehow got a bunch of new users I’d have to cut off signups at some point unless more donations rolled in. I could probably handle a sizeable increase in users first though.
