@sozobe,
I alllllllllmost remember Tsar from Abuzz. I wasn't there all that long myself, being a latecomer, a true newbie - my first effort at any kind of site where people 'talked' - and then being punted out for months and whining myself silly, to, among others, Jespah. Many people told me, via email, to clean my cache to get back in, but I couldn't seem to. I remember craven on abuzz. He probably told me to clean my cache... or my dash.
I remember knowing some people called craven robert fairly early on a2k, but thought it was private to them, and then understood when later on he moved away from the name.
I'm not surprised Brandon wouldn't know - not everyone reads at all times with avidity.
