Flozza! (Australianised version of your name. Gavin becomes Gazza, Barry become Baz etc...) I hope you don't mind me calling you Flozza!
I just have two questions.
1. Do you admire King Canute?
2. Why do you have such an objection to a shortened form of a
pseudonym? We can choose a pseudo, we are not born with it. If one picks an unusual, difficult name and one that is hard to spell, it goes with the territory that mispellings occur. If I had a dollar for all the Yorricks or Yorics I've read, I'd be a rich man.
Thus let me help you out.
No-one whom I've spoken to verbally has any idea on how to pronounce your pseudo. This makes memorisation of the spelling difficult.
Also, it's obvious that it's easier for us to shorten it. Most of us stumble through aware of your displeasure at abbreviations.
However, I think it would save you a lot of stress to forgoe the Canute-like obsession with stopping the tide of typing ease. Mem, Mel, Cloudy, Seph, Dio, Gabe and Granger have all seemingly biten the bullet and assumed - as I do if I read a "Yor", that a nickname is a sign of affection and reduced formality.
Thus Flozza, take this slap of the back from an Aussie wag in the spirit in which it is written.
Have a good day.
