Hey dude,

Welcome to The UEN. Glad you decided to better your game.. and what greater place to start than The UEN. I highly suggest downloading ventrilo as it immensely improves communication which is key to upgrading your game.

As for a race to start off with..

If you are new to the Starcraft scene then I highly suggest Terran for the sole fact the campaign revolves around it. Other then that I suggest playing Protoss.

Either way feel free to add me and I will be glad to help out with what ever I can.
