I've only read one MYM moveset in full before but I still chip away at making my own sets from time to time. It's not required to be a super active part of the community, just jump in, give 'em what you have, and enjoy yourself! My first set (Shadow) was genuinely awful, but my second one (Morshu) ended up making top 50! Plus you teach yourself a lot of good writing skills - if it wasn't for MYM I would not have known what my writing style even was, nor would I have gained the perseverence in my creative projects to nail my auditions for a really good summer camp for the arts.
