We'll create fresh WordPress site with Twitchers installed. You have 20 minutes to test the plugin after that site we'll be deleted.
Twitcher allows people who visit your web site to post wildlife sightings and display them on a Google map. The plug-in only offers a front end google maps geotagging option. The plug-in was inspired by the Sightings plug-in but with lots of fixes to the code. You can display the maps using one of two shortcodes [twitcher-map] which shows a contributor form and [twitcher-map1] which does not. They use different DOM option so you can display one on the sidebar and still call the main map without a DOM conflict.
The plug-in is ideal for wildlife and nature website where they want visitors to contribute to the site. But it can be used for plotting anything you want where you need a front end map function.
While a lot of fixes have been made to get this working there is quite a number of things to do.
