TF2newbs.com is a unique server site for TF2. Obviously from the name the site is geared toward new players, but it offers more than just a place to play against other newbs. Also available are a wide array of forums that are highly active. Here you can find help on anything from basic gameplay to more advanced technical items such as setting up your own server.
When looking at a server page I look for detailed stats and TF2newbs.com certainly has that. They have over ten servers on which to play, but you can easily drill down into the individual server stats. You can even find the geographic location of each server in relation to where you live. You can then dig even deeper and check out individual player stats and compare them to the other newbs that play on each server.
TF2newbs.com is a great site if you are new to TF2 and are looking to become an advanced player quickly. Eventhing on the site is laid out in a simple format and readily available to access. Probably my favorite part of the site is how all the servers have direct links to Steam so that you don't have to enter in the IP through the game itself. I would recommend this site to anyone new or old to the game.
