Caporegime
Somehow I sort of have this picture in my head of a 'typical' OcUK Forum member as being a 25-35 year old male, with a fairly high disposable income each month, and who drives a high end BMW or a Porche!
You and I have very different images of the typical forum member. Many of them can barely dress themselves.
The forums are big because the site is well designed in that there's no flashing sigs or other things to clutter the screen, the mods are good (if not always consistent), and there is a great variety of sub forums to cover a number of different interests.
