Can I make a suggestion? Most Border Collies are actually registered with the ABCA -
http://www.americanbordercollie.org/ And bcrescue.org is just one guy in Texas.
For newbie information on Border Collies, whether rescue or not, probably the best place to go is the Border Collie Boards.
http://www.bordercollie.org/boards/index.phpCaveat, you will not find information on conformation showing of Border Collies there, except for information on why the sponsoring organization thinks it's a bad idea (the US Border Collie Club, the oldest BC breed club in North America - I'm on the BOD

).
The USBCC web site itself has a great deal of information on the breed, history, genetics, health, training, fun reading, and political issues:
