How do I add a contact?

[narcisgarcia]

• Debian GNU/Linux 11/Stable (amd64) +Gnome
• Quaternion from OS package 0.0.9.4c-1build1

I don't find any option to "Add a contact" or invite some individual (who's ID I already know) to chat with me.
Please document and illustrate steps.

The documentation on /-commands is massively overdue indeed... To quickly help - you can just type /join @user:server in the message box (in any room or without a room opened at all).

[narcisgarcia]

For every command there should be some GUI button or menu option.

(of course it's @myfriend:example.net)
/join @user:server

Status bar says:
/join argument doesn't look like a room ID or alias

Sorry, I mistook the command indeed: /join is used to join an existing room, and to message a person you should use /msg or /pm.
