Well Mow, welcome into the forums. Congrats at getting your own key. If you need help, post in the "Help" section. Don't spam, and don't use caps too often. Also, think before you post, read over your posts, use grammar, and use the "Spell Check", it can be useful.
Oh, and with Add-Ons, only download the ones you feel you need, and not every single new one.
Good luck with the game.
Oh, and have a medkit. :)

EDIT: Don't listen to me if you don't want to.
