Needs a location
I use www.5calls.org almost every day. It's fun! They give you topic information, a script, the phone numbers, then you get to check it off when you're done and move to the next issue, like a game. If you're shy, just make your calls at night. It only takes a few minutes. The staffers are super-nice. If you want to Skype with me when you make your first call, for moral support, message me and I'll give you my Skype name.
