literally you just have to be there when it's submitted/open.
there is no special taglist or 'first picks' or anything like that.
if you get something, you get something. if you miss something, then you'll just have to wait for the next set.
why the fuck would you think there'd be anything fancy or special lik e that + i already said that i'd probably wind up making ota adopts/taking art in exchange the next time i actually draw an adopts set
