I have seen this component a few times, but never really understood its potential.
However, I took the plunge and bought it.
It was dead easy to install, straight from the box.
I used the same Google Maps Key that I have for other map functions, and voila, it worked.
For me, this component is a great addition to the many other features of my site, and Users can easily add their own spots for everyone else to see.
Being a non-programmer however, I can sometimes do stupid things... and in my case it was making this available to Registered Users, to stop idiots adding weird things.
The response time from Compojoom was inside 5 minutes! Amazing, as always from the Compojoom team, THANKS!
PS, easy to customize too!
