Then in the "Paths to Other Gardens" I can simply "INCLUDE" the "mygarden-" section of other digital gardens I like, to connect to them and to show to my visitors other possible nice places to visit.
People that want to link my garden to theirs, can simply copy-paste the CUSTOM_ID from My Garden and including it to their Paths to Other Gardens to let their visitors be able to reach my digital garden.
I'll do my best to add my gardens.org page to my digital garden as soon as I can.
