The Basic Meeting List Toolbox (BMLT) is a powerful client/server system for locating NA meetings.
The “root server” is a standalone Website, but “satellite servers” are set up to point to the “root.” This is a “satellite,” set up as a WordPress plugin.
It is very easy to install and use. It has an administration panel that lets you choose a map center, designate the root, set up the map zoom, and whether older browsers are supported.
