WeRelate.org is a promising new wiki genealogy project beta-launched just last month. The site features a genealogy-targeted search engine that singles out websites with names and places. You can help improve the searches by adding new sources, tagging sources for removal, or contributing usage notes for a source already included. The site also features family history articles, which anyone can edit, and user pages, which only the creator can edit. A GEDCOM-import option might someday be available.
As Phil Windley notes, the site's name is "WeRelate.org," not "WereLate.org"—a domain better suited to a support group for habitual latecomers.
