Thank you Fly, I'd forgotten about that. I have been shaking, sniffing and bent double with cramps all morning. Having said that, I've also got more work done in the last three hours than I have in the last three months.
I've forgotten what I'm meant to be doing here at work, luckly nobody has seemed to notice I remember in one of my old jobs when I had just really found "The Internet" I must have done about 1 hour of work a week - seriously..
