Hi Raphaƫl,
Wow ... very good news !
Does anyone know when and where images will be available, and how to use it (tag source, ...) ?
It's now available with Potlatch 2!
Go to http://www.openstreetmap.org/ and hover above "edit" for 2 seconds - a pop up will appear where you can choose "Potlatch 2". (You can also configure your preferred choice in your personal settings.)
Source-tag? I hope Microsoft was intelligent enough to know that prescribing anything wouldn't work anyway.. ;)
Regards and happy mapping, Thomas
