@ JettyZ , it's not an ordinary proxy list site(in fact it's not a proxy list like those you know).
In order to use this service you have to create an account ( i see you created one).
To start submitting your proxy sites you just have to click on the link My Panel which you will find from the drop down menu on the the top of the site.
After this... you have in front of you the whole dashboard with all the functions that you can perform. Seeing that "New Submission" link? click it , but assuming that you don't have any credits yet ... you should first redeem the coupon code that you can find on my previous post.... to do that click the "Redeem Coupon" link
And now you can start submitting your proxy sites till you run out of credits.
