Basically what kraby1 said, but for our classic zombie survival server. From the look of your application though, and references (How long have you been playing on the zombie server? 5 months but many more if you count classic zombie survival), it seems you are applying for our premium zombie survival server. It's called Armies of Darkness and that's under a different section, Premium Servers, on the forums. I could be wrong about where you're applying, but the evidence points to AoD. Also please note, there's a different application format and questions if you re-apply under the correct server section.
-Edit: awwwyea beat me to it, use the links to apply there!
