Here in this forum you can link / mention other users with @[USERNAME].

In my testinstall the @ command is without function, the userlist does not appear. Is there a setting i have to edit before I can use it?

I clicked myself through the AdminCP but I can't find a setting for this.

Bugtracker and a Search in this forum was without any result, but maybe i missed a thread.

No one?

nope but make sure have @ then username without a space like so @mammut

​I do so. But in my local install neither the dropdown appears nor the mentioning is working by typing the complete username by myself.

I was able to find out that i have to avoid the use of capital letters for the first digit of the username after the @ when i want to mention a user.

e.g. the username is Testuser

@Testuser isnt working

@testuser is working

Strange thing! Here on this board I dont have this problem.
