Me too. It's like he's in some dark corner seething away for a couple of weeks, you hear nothing, then boom! A ferocious tirade of uptightness. He needs an avatar though. "Scottish Lovely" Isla St Clair, I think. To go with the Larry part.

I just wish he'd back his points up when he launches his tirades and everybody responds, I managed to provoke him into replying once but I think the rest of the time he's too angry.

Maybe he smashes his computer after every post and then has to save up for a new one, that would explain the absences.
