At first I was a bit puzzled as to why one would post such a message 'here', but I guess including a link to a Lemmy community in a Mastodon toot results in the creation of a post on that Lemmy community.
Neat stuff! (And now, let's see if this results in a toot again...)
That'll work when typing things online, but not in f2f conversations. I thought about 'com(m)' which will work, typed out in certain contexts, but I think that sounds too much like other words in several languages including English to use in speech. But if you prepend 'lemmy' to that it's quite a distinguishable word that sounds like 'lexicon': lemmycom(m)!
There's a lemmycom for that.
