Hi,
just FYI - please cite GRASS GIS when you use it for your work [1].
Addons:
Hint: when citing addons, you can simply use "grass7" in the URL which
is then redirected by the server to the latest GRASS GIS version:
Random example:
https://grass.osgeo.org/grass7/manuals/addons/v.in.natura2000.html
is expanded to
https://grass.osgeo.org/grass72/manuals/addons/v.in.natura2000.html
Best,
Markus
