I've been in the terries a wee while now, and I must say it isn't all that bad.... but one thing that has never been made to clear to me is what is all this G1, G4 stuff about? I have heard it mentioned a couple of times in briefings etc. but never wanted to admit I was the only bloke in the room who didn't know what they meant. I think I have heard mention of everything from G1 up to G6. Anyone care to shed some light?
