@Quickswitch79 Due to the magic of the Fediverse you don't even need to be on Lemmy!
Kbin is another similar system that interacts with Lemmy, and this reply has come from Mastodon!
Although in general I wouldn't recommend using Mastodon to interact with Lemmy communities, it works but it's not what either system is optimised for so it's a bit clunky.
But it's still pretty amazing to me: it's like using Twitter or Instagram to read and reply to Reddit!
