Katara (Patreon)

Couple days ago, patreon sent a mail to me, it is about the raffle that we did on last week. it is outside their terms of use. they think what we did is raffle/giveaway, but in fact we use it to chose the characters for this month. so I think I need to change the word "raffle" to something else.
is "monthly nomination" can be the word or you guys have other good idea?
