Just thought I'd throw this out there. If you're looking for a way to help/support the protesters: Why not order them some food and have it delivered to Zuccotti Park Zip Code: 10006
upvoted you for a specific practicality - too rare and precious element in the environment where many talk, yet a few do.
Though personally i will not order the pizza or do anything else that would leave records trail on the government servers and till the end of my life can be mined with "an active sympathizer to extremists" result.
I found this pizza place that accepted online orders. http://www.majesticpizzatogo.com/
