I needed a solution which would enable members to edit only a part of their articles, without being able to edit the bit that is controlled by the administrator.
This plugin makes it all possible, simple in use as well.
Many thanks.

I've tried several other Google Maps components, they were all very hard to get working and most of all far to complicated for the Joomla end-user, who's often a dummy.
Chris's one works perfectly right out of the box. Besides that he provides a mambot, which enables any end-user to work with it with ease. Okay, for the mambot (not the component) you must subscribe for 15 or 20 dollars, but that's peanuts compared to the quality.
Good stuff, Chris, I'm under the impression that I'm stealing from you.
