Incorportaing Challenges into Patreon (Patreon)

I'd like to consult you guys on something I've been thinking over. For a while now, I've considered integrating the weight gain challenges I do on DA into Patreon. As of yet, I'm undecided as to how I might do it. Polls to vote on who will be featured? Raffles to see how gets to select the next feature? I don't know. But among these options, I'm sure there are a multitude more to consider. I'm more than happy to hear your thoughts and opinions. It's the entire point of this post. I want to do everything I can to improve the work I put out as well as improve the overall Patreon experience.
