i was thinking about strawpage, but i hate that it has to post answers through twitter, and i'm not gonna clog my media tab with other people's art submissions. strawpage currently doesn't have a way to post anything on the website itself that i'm aware of, so really tumblr is the best thing for now, maybe i'll upload the strawpage art submissions on my tumblr too
