Hi Clive.
As you will probably have noted, I am an admin on both these sites.
You are correct that sohc4.net has a head start in this area - they have been going for nearly 15 years and have a much higher North American profile than us.
Whilst it is within my power to copy the contents of that site straight into here - I really don't see the point in duplication. If there are members here who are unaware of .net I can post links to their threads.
What does everyone think? (see, we are more democratic than the Americans....
)
