Yes!! Awesome attitude! Well, it is super easy, literally all you have to do is at the beginning of your video say "This is my entry for week (whatever number the week is of the contest) of Steemit open mic and my username is mattletch." And make openmic be the first tag of your post. That's it. :) There's a huge steem music community on discord as well, do you have an account there? I am incredibly bored on a Saturday night and so am stalking the coolest people on the blockchain. I swear I'm not creepy. Just weird. ha ha
