What about Service post-nominals like cfs*, cfs(t), qss, qs, pscj, etc...
I honestly think that Dii signature blocks should have branch or trade in them so that you can gauge the background of the originator. These faceless e-mails definately lose the advantage of telephone calls where you can work out whether the person on the other end knows anything about what you're discussing. Thus if you are discussing an issue about finance to an Air Cmd staff officer from the RAF Regt then you know that you're in for a rocky ride! (After he's stated the bleedin' obvious having done a no-brain "Estimate"
). That is also why I believe that every trade and branch should have a qualification emblem so that you can see at a glance who you are deling with. Post nominals also help complete this picture.
