I have a Google! group of users who want proxies and I need to keep feeding them new ones.
Post the URL to your proxy site here and your site go out in the next blast.
Maximum 10 proxies per user. Not all of them might go out at once as the blasts are done weekly.
Optionally, you can submit your site to http://www.xproxylist.com with a backlink and your site will automatically be added to the Google! group for free.
