Psalm11918.org has officially launched a community locator service website at MessianicCommunity.net: "Don't travel the path alone." [NOTE: MessianicCommunity.net was folded into the CommunityConnector.net website a short time after this. - ed]
Once registered on the site, visitors can add information about groups, synagogues, Torah study groups, etc in their area. They can also edit the information they add to the site. There is a search tool with a Google map of groups in the area that is searched (address, city, zipcode, state, country, etc).
This is an international locator service with groups from Australia, Great Britain, Belgium, France, Germany, Israel!, and other countries already being added.
If you know of anyone who wants to make their group "find-able" point them to the site and they can add their information.
