Staff Applications

I have no idea where else to put something else like this, so, here's this.
I want to submit a staff application, course, but, whenever I go to the thread I get this, "(You have insufficient privileges to post here.)".
Now, here's my question, is this because I did something, or didn't do something? I have a feeling it has to do with my ban a while back, but I'm not sure.
In the case that it is in fact my ban, is there any way I can fix this or am I just screwed?

 

Solved.
