Hello,
I've noted that the otrs_admin_book v2.4 indicates in the preface that it is "less interesting for agents or customer users."
 
Is there a user manual available for agents? 
 
Something that explains in plain language what "note-internal" vs. "note-external", how otrs handles inbound and outbound emails, what "locked" means, etc?
 
Mark
