The version I've found most useful is "UOD", as in "Unless Otherwise Directed..." As in "Unless Otherwise Directed, I'll be updating the Foo project next week to include the Bar modules..." or "UOD, I'll call Alice tomorrow to update her on Bob's plans..." Works well, concise, shows you are on it and proactive, and works both as a proper status/planning update and/or an opportunity for the person to weigh in to change course... (and documents the chain of events).
