First, this belongs in the General Info
part of the tourney forum, but the (easiest) answer is game finder
go to game finder, there is a drop-down list thing for tournaments. Start typing in your tourney name (so you don't have to scroll through all 50 billion of them), then when yours is highlighted, click search.
If you want to only look for games waiting for players/active/completed you can check the corresponding box at the top of the game finder page (before you click search)
Also, if you are interested and have firefox (if you don't have it, you should honestly download it just for this site, I did, normally use chrome) you can download the Watch This Game
add-on, allows you to click "watch" on any game, then you don't have to go to game finder every time. There are other add-ons that help for tourneys as well, you can find them all in the Tools/Enhancements forum
