You may not get a reply to your application, just try to log on the server. If it continues to say that you haven't been whitelisted, then you should apply again; HOWEVER, do not apply with the same thing as you previously did. If your application was not accepted, it's probably because you didn't provide proof of your work. Make sure to provide proof next time you apply, and if you did in fact supply proof, then you should improve. We rarely turn away applications with builds, but when we do, it's because of just a complete lack of skill. Improve and come back.
