bgb, well done ..
You have done a great job on the pool and its success is evident by the number of users you have succeeded in bringing on board over the past few months.
I certainly think that your idea of operating team pools under subdomains within the grcpool.com domain (usa.grcpool.com, uk.grcpool.com, etc...) is a great idea. I must chat to you about that in the near future.
The only way is up!!
