Constant Content

I figured out my problem... There's a button that says unavailable right above the line: desired number of articles per week. When I clicked it and changed it to available the apply buttons came up. Previously they were all grayed out and said unavailable. Now I just need to figure out how to apply ...

I have recently had the required 10 articles approved. I have been checking around the site and came across the stuff about the writers pool. When I go to this area, everything is shown as unavailable. How do I change that?

Thank you,
