I also had a look at https://feddit.org/c/main but my German is very basic, the most interesting topic seems to be a tutorial on how to migrate accounts from feddit.de to feddit.org
I would much rather someone else takes over moderation, yes. Both because of various federated moderation bugs in Lemmy making it hard to moderate a community that isn't on your home instance and because I have way to many communities that I moderate already.
If needed, I would be willing to help with moderation, but not be the main moderator of such a new community.
/r/europe became pretty much a Nazi cesspool and I feel on the fediverse it could quickly become a Tankie cesspool. I personally would not have nerves for that either. Would be sad to see this community die if the instance inevitably vanishes though.
It's presumably mostly taken from the original feddit.de instance. Maybe something to talk to the admins about. Personally I think a European instance makes more sense than a purely German one.
I clearly meant the standard issue text below that... But since you're apparently here to look for pedantic arguments I'm gonna end it here anyway now.
