I was rejected, but to be honest, I didn't expect too much. My project is in Panama and is in Spanish, so my chances were low to begin with. But I was happy just to get a chance to participate and a great forum to bounce ideas.
I loved the idea! I would really make the subjects stand out a little more. It seems to me your site is all about content, and at the moment content is not king. Make the content column stand out more, and probably use different fonts for subject title and description.
I love the idea, and I think making the subject list stand out would make your sight more appealing
Good luck to all the projects!
