I thought I might as well register my bike stolen with this community, sad though it is 
It was a Gary Fisher Advance XC Hardtail, like this: http://www.mtbr.com/cat/bikes/xc-hardtail/gary-fisher/advance/prd_363422_1527crx.aspx
Distinguishing Features:
Well first off it's blue rather than the red in the picture!
It had sticks on it from Thomas' Cycle Revolution in Colchester, Essex
Both front and rear brake pads were very worn, I was about to get them changed
The selection lever which allowed you to lock out the front fork had cracked and snapped off at the end.
A slim chance obviously but if anyone does see it, I'd be very grateful indeed to get it back!
