@ada I think I heard somewhere that ! means that the post wont be public but just targeted at the specific person or group. It can be seen by other though if they have a direct link to the post.
@anders@venera.social@ada@lemmy.blahaj.zone So, you posted this comment from Friendica, directly to a lemmy community, something that I didn't know was possible, and haven't been able to replicate, so all bets are off. I have no idea how it works :)
(I'm replying twice to test things. This is a reply from Calckey)
If you wanna do that then the post needs to have a title and then tag the community in the beginning of the post with either ! or @. Feel free to send a link to your post here if it doesn't work then I might be able to tell you what's wrong as I have tested it quite a lot now. Lemmy's compatibility with other platforms isn't so good in my opinion so it doesn't take much mistake for it to just ignore one's post.
I imagine the @ works fine as well, as long as there isn't a user and a community with the same name. Not sure what would happen then, and haven't been able to test that
