There is a tool to help migrate communities from one account to another to use when moving yourself to another instance called lemmy-community-copy.

It's not a far stretch to imagine that something like it could also extract and package a user's communities to share with others.

USENET was a mess too, though... The entire Alt.* hierarchy was an attempt to route around censorship and I'm pretty sure I recall lots of duplication of groups. /derail

15Redstones@feddit.de created a bookmarklet to help scrape subscribed communities, but I haven't tried it yet:

Subscribed communities copyer

Bought Ultra last week as a thank-you. Will buy again!

WTF?

Best do it early while you can still get the same username...

Could this be modified to package up a user's communities so that it could be shared with someone else? here's someone asking for something similar.
