As someone who submits articles on at least a semi-regular basis, this site doesn't really stand out as a top-notch article site.
There are a few reasons for this:
1) It's an Article Dashboard software-based site. I don't have a problem with this in and of itself, but the basic skin has some cosmetic deficiencies and you would be well-served to at least customize it so it looks and feels different.
2) You have the most recent articles, but what about featured/popular/really good articles? In other words, the cream of the crop. Put those first.
3) Whooooooooooooooooo aaaaaaaaaaaaaaaaare you? Who-ooh! Who-ooh! All we know is your name. Where's the site based out of? What's the mailing address? I know it's only a free article site but a little more info is in order.
Having said that, the base functionality of the site is sound (like all AD sites). You just need to do something to make it stand out and be unique, which is an absolute bitch in the niche you're in.
I submitted an article, and everything seemed to work okay. If you want some more, feel free to take anything from
