One of the smaller quality of life improvements in 0.18.1 is now lemmy-ui will look for text that looks like a community like !community@instance.com
and automatically links it to your instance’s community page for ez subscribing.
So if you just type in a post or comment !community@instance.com
it will link to https://beehaw.org/c/community@instance.com
when you post it.
If curious, here is the change request that added this feature. https://github.com/LemmyNet/lemmy-ui/pull/1462
Damn good work, people.
