Tech Soup, the "mother" of NetSquared, has just launched a Net Neutrality toolkit to help you get more info. about both sides of the issue. You can also discuss Net Neutrality in the Tech Soup forums.
if you are for Net Neutrality, Save the Internet, has lots of actions you can take as well as a map that tell you which Senators are for or against Net Neutrality.
