Hi Nick!
First thanks you for let me try the plugin with the add-on to allow visitors to add map markers.
Well, the plugin add-on work very well with my wordpress site, just what i was looking for, a simple way to allow visitors to add map markers, now comunity feeded websites are very populars and people need to share places locations easily and your plugin can do the job very well, i know still beta so i send you my sincerely feedback.
Pros: Easy to use, Easy to setting up, first plugin that i know can do this easily, work well with different maps on different pages, same map can be used in post and pages using the shortcode, every one can add markers, quick spam protection just take a click to users confirm they are humans.
Cons: Still beta I know it so these are my suggestions to you>
-Users can’t fill all forms information just three, title,location and despcription, so the admin has to ask the extra info to fill it by himself. Suggestion: this is easy want to code just lets user to fill all info needed.
-The location: There are so many countries that doesnt has a very well documented google maps, so you can put the street adresses on the location form but the marker apears miles away, so the add-on need a minimap marker picker where the users can move the marker exactly where they want and save it, very useful improvemnent.
-The admin control for users markers, let do more things to registered users and 100% control of markers submmiting.
By the way:
A money maker tip: Google MAP API let developers or publishers insert Google Adsense Ads on google maps, this a very useful tool if you want the atenttion of adsense publishers.
I hope you can do these and others improvements to your plugin, waiting final realese to buy it, Nice work keep going.
Sorry for the gramma errors, im still learning English( i dont like to use google translations tool so i do it by myself :-)).
Best regards!
