I may purchase your extension again as I need it for its openstreet map integration that your joomla competitors won't offer but I would like to know about something :
Jcomment has 2 modules to show the latest comments and in it there is a source settings that links to the plugin folder of jcomment where a my map plugin is not present.
Coud you have a look, the plugins are very small and have in it like 1 SQL Query and it would be very profitable for many people to see the last commented places of a category in those modules with a link to access the place.
