I like the light theme too!
I'm contemplating joining but I am unsure of whether I'll have too much other work to do. I'd like to participate cause I recently got RPGMaker MV and would like to learn more about it. I'd say I'm more interested in the art element of RPGs than the stats and mechanics, though it'd be fun to come up with a gameplay feature that makes the standard RPGMaker a little more unique.
