Constant Content

I submitted one that was for requested content and a few others that are just free articles

Thanks for your site. I love this site already. I have submitted a few articles. How long does it take for them to be approved?

I am new to Constant Content and had a question about the requested content.

When writing these articles, do you just submit to the category that the article would fall into? Or is there something special that needs to be done if you are writing one of these requested articles?
