and I will not ask for the meaning of 20047 or the Englishy greenish color 😉
It’s NO in ASCII and I’m not a native English speaker… and this thing doesn’t have auto correct, underline or suggestions 😒 (Jerboa).
The correct way to share a community on Lemmy (so that apps recognize it as a Lemmy community) is with an exclamation mark, as in your last example. The search in Jerboa (as is with other apps) is broken, doesn’t work like it should. Use the web UI search on your instance, you’ll find the community.
