Hiya Darren,
It's very pleasing to see that ADUK has progressed further and that your efforts are yielding some reward.
I think it's a good site and it deserves to succeed, but when I last looked at the membership figure (quite a long time ago admittedly) we didn't seem to be acquiring new members at much of a rate. Why is that, I wonder, when PistonHeads seems to have zoomed from about 30,000 when I joined them about six years ago, and last I heard it was well over the 100,000 mark?
Membership numbers aren't the whole story of course, but I feel sure this site could be helpful to a great many more road users if only they would come on board. Maybe some of the lurkers will come out of hiding and tell us what they think.
BTW, if we're correctly told that 75% of statistics are made up on the spot, which one of your four figures is right?
Best wishes all,
Dave.
