As a part of his NYU thesis Fred Benenson has built this new activist tool, Cause Caller.
create a cause, and enter the names you want to contact. Now you can click to call immediately. Send everyone the URL, and they can start calling too. All calls are free and completed over the Internet.
Cause Caller is a VoIP application combined with a wiki of causes and contacts. The more causes you and others create, the easier it is for everyone to get involved in participatory democracy
This is great. He needs help filling out the wiki with state level politicians. Help out if you can.
