First off, let me just say it is really late and this thread could quite possibly be misinterpreted by a lot of readers in this site,- but this little project of mine was the result of a last-ditch attempt for what may be the ONLY WEEK in which we have a window of opportunity to pass the Dream Act until 2012.
Operation Fax Barrage-
These sites www.faxzero.com(limit two per day) www.myfax.com (limit two per day) http://www.freepopfax.com/
provide users a way to send faxes online for free. Meaning you only fill out who it's going to, their number, your name ("Dream Student"), nonpersonal email, and, in the case of faxzero, a number ("9999999999"- that's ten numbers folks)
Add an attachment (See mine- it's just a pdf I created using Google Docs that says "End our nightmare! Support the Dream Act!")
...and voila. Your fax has been sent. Not before finishing the last step, though, which is to click a link sent to your confirmation email that you want the fax sent.
