MM-Pro licence question?

Hi there,

we’re looking for a new MapsMarker-Pro License and i have a specific question.

We’re running several WordPress Installations on our server, including one big Multiblog-Site. At this time there are more than 30 single installations – all with seperate database, logins, etc. but all located on one server (www.bildungsblogs.net) accessible via subdomains or folder-path (eg. bildungsblogs.net/wp/blog1, 2, …)

Nearly half of them need MapsMarker, so we’re looking for the right license model.
Do we need in this case the “Personal” (which features 1 domain as in our case) or do we need the “Plus” for 5 domain?

Best regards and thank you for your help,
Marco Teufel
