Dip CS (Open)

I received my certificate today for my Diploma in Classical Studies (Open) which i was awarded after passing AA309 last year (and A219 2 years ago). I can put Dip CS (Open) after my name if i want though i've been able to put BSc (Hons) after my name for the last 14 years but haven't done it yet. Well i tell a lie, it appeared on my business card once though i never actually got to give any of these out so that doesn't count!
