What does the message Usermessage-summary (“Leaving system message.”) mean?

And the message Usermessage-editor (“System messenger”)?

• Usermessage-summary : the edit summary for a system message
• Usermessage-editor : the user that is the editor of system messages

What does "Leave system message" mean in that context?

Any message that is posted because of a system event - whichever you can think of. Currently only a failed asynchronous upload is notified as far as I know.

"Leave" should be translated as a verb, as in "To exit", "To go away"?

I'll update it to "Leaving".

Verb ar not verb isn't an issue for me. But the verb "leave" could mean exit, e.g. exit a program or add, e.g. if somebody calls another person by phone and this other person is not persent, the caller can leave a message to the other person to inform him about something. What sense is meant here?

Leave in the meaning of "to let remain or have remaining behind after going".

Thanks.

Why not use System message editor instead of System messenger? I didn't know the word messenger used in the sense of message editor, a person who edits messages. For me the word messenger denotes a program, not a person. Of course I know that the general meaning of this word is bearer of messages.

Is this alternative definition of 'system messeger' correct? A system editor which leaves a message notifying that a system event has happened.
