so… 1 - how is the compatibility to link to instances in other feds? (kbin, mastodon…)

2 - its possible to sub to a community on other feds inside lemmy, or is required to setup a account there?

some folks from our scope have instances there, but I don’t know if someone here on lemmy can sub to their feeds and how they can link properly so cross posts works as intended

yep, those subs will see a slower fade as their users need to make sure that there is a platform to assist them alongside their mod team, be it here or in other platform, 100% understandable
