What now? Next steps?

I checked out the built in features on Outlook Web Access (which is the lowest common denominator) and I only see low priority and high priority. If we go with the tag idea, it sounds like we are thinking the following tags would be helpful
*Response Required
*Non-Urgent
I don't think we need to be fearful about recommending these as there is no real requirement to follow the recommendation. To the degree people use the tags will be up to them - the more that do the easier it will become. If the tags are helpful - they will catch on.
I would also like us to consider the protocol of identifying emails that are destined for the receiver only by putting their name in brackets e.g.
subject: Staffing= denotes a general email, subject: Staffing (Bill) or subject:Staffing (MY Council) = indicate specific audiences. What do you think?
