Drawing mashups is free, the archive is free, and the daily leaderboard is free. It will stay that way. If you would like to help with what it costs to keep running, this is the one place to do it.
Hosting, a domain, and a copy of the results archive that has to be refreshed after every race weekend. That is the whole budget — there are no ads, no tracking scripts and no investors expecting a return.
It is not a subscription and it buys nothing on the site: not extra draws, not a badge, not a place on the board. The leaderboard has to be the same game for everybody who plays it, so supporters and everyone else are ranked identically. Give because you like the thing, and only if it costs you nothing you will miss.
