Another likeminded group fighting dominionists...
http://www.religiousrightwatch.com/
Methinks a lot of good could be done in sharing of info with them, as well as links to anti-dominionist groups.
A lot of the stuff is also linked here, I know...but I figure the more networking we can do, the better off we are in fighting them (it's something the dominionists have done distressingly well :P).
There is a sister-group, http://www.talk2action.com/ that will also be useful to work with, IMHO.
