If you've created a web site of your own, joining a web ring can be a great way to build traffic to your site and be found by people who are truly interested in its subject. You'll just have to find a relevant ring and request to have your site added. It doesn't matter if your page's subject matter is conventional or offbeat, chances are there's a ring that it will fit into nicely. If there isn't already a ring on the topic that your page covers, you can start your own. So you should consider sending e-mail to invite the creators of other relevant sites to join your little web ring.
Web rings are an increasingly popular phenomenon.
They're useful for surfers and good for web site creators, too. The next time you happen upon a page that's part of a ring, go ahead and use it to explore.
