Message info please
- Usermessage-summary : the edit summary for a system message
- Usermessage-editor : the user that is the editor of system messages
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"?
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.
