Thank you! I'm shockingly bad at forums so can't promise I'll be anything more than an occassional poster and lurker - but it is lovley to see so many familar faces (user names...) after such a long time. I think it's been nearly two years... and I joined in 2005 which was a lifetime ago.
Hi & welcome back.
As far as I know it's not possible to change one's user name unless one opens a new account.
It's best to WWmail David Bruce and ask him.
