Crowds is a new system for protecting your anonymity while you browse the web. We have recently obtained a release for the code from AT&T and have been testing the system with a handful of volunteers. Thanks to their efforts, we now feel more prepared to support a larger user community. So, if you are interested in browsing the web with better anonymity than the Anonymizer, check out http://www.research.att.com/projects/crowds There are two steps. The first is obtaining the code. After you accept the license agreement, expect a 24 hour turnaround to receive the code by e-mail. Second, if you would like to join our crowd, fill out the registration page, and expect 24 hours before you are admitted. (These steps can proceed in parallel.) The system requires Perl 5.003 or higher, and has been tested on SunOS, Solaris, and Irix. Our next target is Linux. - Mike Reiter and Avi Rubin
