I'm brand new here (Wed April 25) and i'm wondering how to actually do a tournament. Do you sign up on the site or do you just show up to the tournament. also, the tournament list is VERY confusing to me. (symbols and abbreviations and such) help would be greatly appriciated.
Based on context clues, I assume that when you say "how to do a tournament," you mean how you join/enter.

Generally speaking, all important information, such as schedule, address, cost, and the like will be listed at the beginning of each thread. Unless they explicitly say, "You have to preregister (which is almost never the case for anything smaller than a national event)", you just show up to the place at the specified time and pay whatever entry fees they ask for.
As for abbreviations and the like, it tends to be pretty straightforward. Above the list of threads, you can click on a specific area (if your location is accurate, Missouri would put you in the Midwest), and it will only display tournaments in that area.
Do you have any specific abbreviations you don't understand?
