This HTML has hypertext which allows visitors to click to the next or the previous web site in the ring. So each Webring member gains from the process. You send visitors to other people's sites, and they send visitors to yours. And because Webrings are collections of sites with a common theme, the visitors you get are likely to be more interested in your site than some of the casual visitors you get from search engines. Some of them are general guides, some may have a specific theme - such as entertainment.
Full instructions are on the Join page.
Your site will then be reviewed and the Webring HTML checked. If it is all acceptable, the RingMaster will add your site to the Webring.
