Hello all!
A few months ago I posted a thread on here about changing my name back to my original name after initially changing it when I got married. My DH had a double barrelled name of which I was planning to drop one half and add my original surname to instead (e.g. Smith-Brown to Smith-Horton).
Well, I have since changed it! Indeed, following on from some thoughts raised by the thread, I decided go the whole hog and just have a totally different name from my DH - no barrelling, just the surname I was born with. I'm extremely happy with my decision! 
Anyway - then began the gargantuan task of taking my deed poll (as usually you need a decree absolute to revert to your original surname...) around getting the name recognised. I have run into something of a problem with the University which I am currently a PhD student at.
University email addresses at my institution are based on a username which is based on your initials and a number to distinguish you from people with the same initials. So the username assigned when I started was, say, "rsb21". I imagined that on changing my name my username and therefore my email address would change to reflect my new initials ("rh32"). As I want to be able to hand out an academic email address to students, new colleagues, and people I meet professionally outside of the university, it matters a lot to me that it 'matches' the name I have chosen to be known by.
I have since been told that this is "just not done" at my university. Apparently, "ladies" who change their name when they get married just stick with the same username - but, most people do so are staff members, who use a different email system which allows them to have an alias -- so to all intents and purposes they could change their email address, they'd just use their old initials when logging in to things on the intranet etc. However, as a student I apparently can't get an alias.
So, my question is, how stubborn should I be on this? Every sign points to the change of username being possible but fiddly -- and because it "isn't usually done" they are reluctant to open the floodgates. I feel as if the staff in the IT office feel that I am being unreasonable and making a fuss over nothing, but I feel really incredibly strongly about this. Am I being ridiculous to want my email address to be made up of the initials of the name that I want to be called? Or am I just being over-emotional at the end of the week?
