We don't have a ladder, but we have a pretty good idea of the rankings within smash club. We have 2-3 tournaments for $5 per semester. It sounds like a good idea to host biweeklies for $1 though.
It's not necessary to leave the TV's there, but I've left my DBZ tv in one of the offices for a couple years, eventually they ran out of room because they already have so many tv's, so I had decided to take it back. I pretty much bring a TV manually from my house if one is needed, I personally own 3 CRT's.
As per bringing the PM group in, I messaged Dura Mater, but he did not reply. Perhaps he's just busy, and they're open to playing melee. I'm definitely open to playing PM more.
