Very sorry to hear that, a legend has passed. Just watched LGR’s react to the Computer Chronicles 1987 Christmas Episode the other day… I may need to schedule a Computer Chronicles marathon soon in light of this news.

You don’t because everything here’s based on communities while Mastodon is on individual users. If you’d like something that does both in a single platform I think Mbin would be the best bet (although you can interact with Lemmy communities using Mastodon and other microblogging platforms to some extent)

Another vote for NeoDB. It’s been very useful for me and more people on fedi need to know about it.
