That means you have been rejected. The only thing you can do is create another application and send it in. Persistence is a good thing when applying, don't be shy and send in a new application once a month or once every half a month if you want to. If you don't have enough dedication to keep applying then you won't stand out as an applicant, they may say no at first, but over time their opinion of you can change if your applications and public image are good (by good I mean you haven't been banned a lot).

Also, while it isn't guaranteed you'll get an answer, you can approach a member of the staff in IRC and respectfully ask them about your application. Things like what you could improve on and if there were any aspects of it that caused them to turn you away. I would recommend asking a staff member that you're friends with or at least familiar with to an extent.
