No worries at all! Gotta get you settled in somehow 😄
I’m not sure what you know about Mastodon but it’s a microblogging thing (think Twitter).
So, Mastodon users can search for Lemmy communities, which appear to them just like a regular Mastodon user account. They can post to the community by tagging that account. If they follow the community they’ll then see new posts and comments show up in their feed like regular “toots” (tweets). As you can imagine if they follow a busy community that gets spammy fast, but it does work.
From the Lemmy side, we can’t follow Mastodon accounts yet afaik. But we can reply to posts and comments coming from Mastodon users, which from our side are formatted just like regular posts and comments in our communities.
Hmm I better add something Futurama-ey so I don’t get in trouble.
