Looking at the signup page, I saw many non-regulars entering.
From my experience playing/running ggpo online tourneys, the most annoying thing is unable to connect.
You’d often have two guys blocking the whole tourney because they cannot connect.
Most likely it’s because their ports are not forwarded correctly (they will tell you it’s forwarded), and they were playing fine with other players because the other guys set it up properly.
I strongly suggest requesting all participants to test their ggpo setup before friday and make sure it works properly. Instead of waiting until friday when kuroppi enters you into the tourney and then you get stuck.
forward UDP ports 6000-6009 to your computer
follow instructions from http://portforward.com/
download open check port tool
test UDP ports 6000-6009
if everyone can do that and test it prior to the tourney, it would probably make this a successful tourney
(if time permits, during the ping checks, the participants should challenge sabin from EC and cigarbob from WC and make sure they can connect)
