another [ahem] technical question

How do I go about finding a community by the name of the community? Bear in mind that I don't have a paid account and the advanced search is not available to me. When I go to "find communities" it wants an interest, not the name of the community, and when I type in likely interests, the community doesn't come up.

The one I'm looking for in particular is "SpecificMarkets," but I'd like to be able to do this in general, as well.

Thanks!
