I'd like to help if I can
I see you're a new player. Welcome! We appreciate the help
The process is like this. You (and others) add only match results and the occasional new player. You are not allowed to add tournaments (although it will be possible for you to do it because the site doesn't have so many administration layers). kingroger is the one who adds tournaments. When you see a tournament that has 0 matches entered you can start on it. Preferably you should post here once you are done with it.
I'm the technical administrator, I fix mistakes that can't be fixed on the site (like deleting something) and I generally maintain the site.
Please contact kingroger for the password and further instructions
