Hi. Unfortunately, the way this game's lobbies are set up, you have to be really patient until you can find a game. It doesn't list games in progress, and games tend to only sit in a joinable lobby for a couple of minutes at a time, which, coupled with the low online population, means you could have to wait up to 20 minutes for another game to start (if you started looking just after one started).
There's a load of guys on here I'm sure would love a new member to their ranks who seem to play regularly... Also, they sound like the kind of guys that would enjoy helping you improve instead of just hammering you until you quit. See if you can get some of them added - I'm sure many of them have posted their gamertags a few times if you read around...
Good luck
