The short answer is family illness. I decided that if I was to stay with QA at all, I would have to stick to the games and avoid the forums at all costs. They are great fun ... but far too time consuming!
Anyway, I have a little bit more time on my hands now, and so I will gradually plough my way through all the posts I missed over the next few weeks. I'm sure you have been having lots of laughs without me!
