That's what this does:

[Some text here](/c/community@instance.here)

Tap the 'more' skinny hamburger menu just ~~above~~ below this message to 'view source' of the below:

blah blah blah links to asklemmy@lemmy.ml

Actually..better, here is one for an instance that is neither yours or the one you posted into:

blay harg vlar

I thought it worked if you just linked /c/asklemmy@lemmy.ml
With the only caveat being that users on kbin will need /m/asklemmy.ml

I would normally test the crap out of these before posting since I really don't know what I'm doing, but I'm on my phone and mostly busy at the moment. Sorry if it doesn't work.

Once your Lemmy web frontend upgrades to version 0.18, the following should all auto-link with no extra syntax:

• !community@server.com
• /c/community@server.com
• /m/community@server.com
• /u/username@server.com

These should then all link to the instance you're currently on.

Note: because this is implemented in the frontend and does not change the underlying data, other Fediverse clients will not show these the same unless they also implement this themselves.
