"Strange .. they have no place where you can register. How do they keep track of their bloggers?"

Go to:  http://www.gopbloggers.com/

On the menu at the top of the page, click on    "Grassroots"

then on the new page look for the 2nd menu from the top, click on:    "Join The GOP Blogroll" 

That's where you can sign up.

You know .. it's probably a silly to ask .. but don't you think clicking twice to Register is odd? Why not just have a buttom "Join the GOP Blogroll" at the top of the first page?
