Well first off all, you need to have all the requirements wich are:
minimum of 20+ -post.
U need at least 100 game hours in our servers
and you need to be 3+ months registered on our forums.
Then, u might get an invite by an admin if your behaviour is good, and when admins think you will be a good addition to our community.
To help you a little bit, u could log-in on our Teamspeak server and get to know other members. Be a good sport, we don't like people with a bad attitude.
Hope you have all the information needed.
If you need to know anything else, I am sure anyone around will try to help you out. Best regards, And good luck!
