Paul has just released a new feature on the entries page. Now you can copy coordinates, display the point on an OSM, Google, or Grottocenter map, and also display these coordinates in the coordinate system of your choice. He has also added a feature that allows you to right-click on the map to select your coordinate system and copy the coordinates into it.
Starting April 23rd, when you create an account or log in for the first time, you will receive an email allowing you to confirm the validity of your email address. This verification will allow us to offer you, in a few weeks, a service that will allow you to communicate with other users without your email address being shared. Thanks to Zouhair for this excellent work.
