The main thing is people can get information on the web anywhere, its not hard to find. What they cant do is ask questions if they are not logged in. They also cant see anywhere you guys actually discuss technique if you do.

I should also mention that for builders on the site to have googleable free to read well written reviews on their machines is very good for them. If all the reviews are locked down noone will land here by searching machine review information. A common search term that lands traffic here is reviews of the bishop, the neotat and the rapier machines.
