How It Work :
1. Turn Off your pop up blocker
2. Enter your website address, using http://
3. For Max Pop and Max URL, its up to you.
Note :
Max Pop = the number of pages that will appear, if your connection is good, you can choose 10 or more, if bad choose 5
max URL : If you want to submit to all site, choose all, but it will need longer time. if you choose 5, you only submitted to 5 site only

hope it will help
