What I did:
File -> Add new account
"Create New XMPP account"
Username: Firstname Lastname
What happens on latest nightly:
We failed to create your account due to the following error: No user ID provided"
What a friend of mine using Jitsi 2.2.4603.9615 reported to happen:
We failed to create your account due to the following error: Could not
Unknown XMPP error. Verify that the server name is correct.
What should happen?
It should inform the user that
- the registration failed because of a bad username
- give advice on what characters are allowed
- list the characters that caused the problem (best, but actually optional)
