"At revspace.nl we are running on volunteers only ... Every week there are a few (monetary) bounties that can be claimed by members (vacuuming the space, taking out the trash, etc), which can be signed-up for. The volunteers who do these tasks then get drinks-credits for their work. So far (we've been doing it for a couple of weeks), this has been working nicely, even if it's still mostly boardmembers and the usual suspects doing the cleaning, they at least feel somewhat compensated for their time now."
