Welcome to the boards, Flock! I hope you enjoy your time around here! :)
You mentioned how you're a competitive Melee player. I hope you've been enjoying Splatoon just as much, because we need all the help we can get around here!
Around here, we're all trying to advance the competitive Splatoon community in every way we can. Not sure if you've been around here or not, but the first official tournament, Ink or Sink: Testfire (link in my signature), is going to be happening soon! While the current bracket is full, it will be interesting to see how it plays out.
(btw, I'm assuming that you're completely new here. You may have already seen Ink or Sink, and heck, for all I know, you're already registered. I don't know, I just thought I'd let you know in case you are unaware. :) )
