My first item (PHP Script) has been rejected, please help me to make it better.

Envato Quality team said, We have completed our review of “Login and Register with Facebook PHP SDK” and unfortunately we found it isn’t at the quality standard required to move forward, and you won’t be able to re-submit this item again.

Its working fine and clean code, whats wrong with the script? Can anybody help me what i should do now and can i re-submit it after improvement?

Here is the demo: http://www.skyitdevelopment.com/login_with_facebook_php_sdk/

Problem is that there’s already items to do this - a lot of them in fact. You need to go through them and make sure yours has more features and better design than all of them, otherwise there’s no point adding just another facebook login to the market.

You can resubmit it after a substantial amount of changes.

Thanks for your advice
