Online Communities are usually classified by topic.
First, please search the entire directory for your featured topics and see if they have a "Chats and Forums" subcategory. Submit your category there.

If your site is focused more on a geographical region than a topic, search the Regional tree for your locality. Submit your category there.

If your members almost always use a language other than English, search the World tree under that language.

If nothing above works, then submit your site to "Computers: Internet: Cyberspace: Online Communities" so that it may be categorized appropriately.

A general category for all adoptable internet or computer-based pets, whether simulated or graphic.
