Categories arrive as and when the demand is there. (The latest, Science, recently won a poll to appear on the site.) Anyone else share pjm007's enthusiasm for a car category?
I suppose a 'cars' category would have more questions than a 'ghd's' or an 'alba casette player' category, however there are few enough questions about cars not to overcrowd the 'how it works' category...blah blah blah natter natter natter.. = NO !
