Admin is free, yet you do not apply directly for admin, or ask for it. You must apply to join the community via the recruiting office forums for your preferred division, from there you may put on the =(e)= tag and represent the community.
As long as you obey the rules while wearing our tag (and have fun!) you will get noticed for a promotion to an admin in no time!
And as I'm sure you will be told many times, the best way to NOT get promoted is by asking for one.
Feel free to post or PM me with any other questions you have.
