MayFirst is waiving initial membership dues to Occupy related websites.
May First/People Link is a politically progressive member-run and controlled organization that redefines the concept of “Internet Service Provider” in a collective and collaborative way.
Just go to https://mayfirst.org/joinus to fill out the form and describe what work you are planning to do. They’ll help you set up a domain, which comes with email accounts, lists, and full server access on encrypted disks. Do take into consideration, Mayfirst support is a group of members that are volunteering time to assist you and this will take more time than a traditional commercial server. However, your site will be protected on a server ran by people who are invested in activism and understand the value of security for sites involved with the movement.
