All
Today, on request, I added the 'Real Name' field into the profile. While our pseudonyms are all perfectly valid (?!?!? ) it is a little more personal to be able to use a real world name when speaking to each other, assuming you are happy with that and wouldn't prefer to keep your internet anonymity.
So with that in mind, it's by no means mandatory, but if you want to add your real name, then you can.
Cheers
Mark
