How can I request a community?
On Reddit, there was r/redditrequest where you could request subreddits that were abandoned by moderators. Where can I request a community, just like how Reddit handled subreddit requests?
Message/ping an admin and explain your case
It should also be made known that you are free to create communities yourself. There is a create community button on the home view of Lemmy.world.
I think OP wants to request to be the mod of an abandoned community.
