Blossom, it doesn't really - it's just that if anyone knows my old user name they'd be able to find me very quickly; by changing it it'd slow them down a bit. Not fooling myself, I'd get found again soon enough, but as I say, it'd take a little bit more effort. I guess the only way really is to create a completely new account and ensure no references to the old name. That's why I created a whole new ID for the issue(!) this time last year - I know my mum knew my original userid at the time, and probably a few other members of my family.
B&M, what a nightmare. Hope it's uneventful on the day, and definitely yes to the G&T!
