Thank you :) and yes, Nick (NAR) is responsible for my being here.
I wouldnt know how to go about introducing myself... I'm a unix programmer, if that helps. If I vanish for a while, it's because I'm asleep, usually after spending a few days sitting infront of terminals at university.
Congratulations on the amazing work - I'm impressed with gridcosm. Oh, and feel free to call me Tom :)
