I have my own new Yahoo Group consisting of 750 Subscribers along with MANY other unmoderated groups I post to with well over 20 000 Subscribers. There are probably way more subscribers, I just haven't added them all up!
I have an Auto Poster and Post Proxies throughout the day. So I am helping out fellow NetBuilders by simply including a few of your URLS in the Newsletter blasts.
This is Free of charge. If you would like to have a few of your Proxies blasted, just post them up here.
