Hang on, I don't see how reading the C2 Wiki qualifies as "pairing with Ward". Boo hiss. -- OliBye Since your objection is the first use of the word "pairing" on this page, what exactly are you complaining about? The heading says "The spread of XP to members of the ExtremeTuesdayClub": no mention of "Ward Number" there. Anyway, for those of us who were the earliest adopters of XP, working on a different continent from C2/Ward/any other rock star at the time, and before the formation of any UK XP community, how exactly were we supposed to learn anything by pairing with anyone, there being by definition no-one to pair with?

So is XP to be disseminated using the Japanese iemoto system? ;-) (See A system of licensing ...)
