Webrings are a groupings of sites linked together and sharing a common subject or focus.
Once you are finished viewing one of the sites you visit in a webring, you can easily go to the next in line or any random site in the ring.
It's easy to add your site to a web ring, but as a MySite member you can also create your own webring.
Webrings are great ways to build traffic to your site. Just create the small navigation bar and add it to your page, then invite others to join your ring.
Once they do, you'll all share in the reciprocal traffic.
