I've been going to the Fan Creation forum on HearthPwn just about daily for years now. It's easily the best part of the website in my opinion, and pretty much the only reason I stay on, as well as card reveal season.
One of the most disappointing things about HearthPwn was that there wasn't very much emphasis put on the fan creation community. News articles regarding the fan community or their competitions never received much attention. Not everyone is interested in creating cards, I get it, but I think it's still possible to do something about it. I have some proposals.
Over here, Sylicas made his/her own column called "Archivist's Lore", where he/she brings up some cards and talks about how they relate (or don't) to WoW lore. It's a really nice read. One proposal I had was to have something like this called "Fan Community Spotlight" or something like that, name is subject to change. In this column, we look at a custom class or card set that someone has made, interview that person and talk about the process of creating the set. Anybody could choose to run it if they want to, doesn't have to be me. Doesn't have to be run on any sort of basis either.
Over here, I also made a guide on creating a Basic set for a custom class, which I copied over from HearthPwn where I also posted it there.
