I figured I would share this with the forum. If you're like me, you don't have a fax machine and don't care to sign up for some account and pay a per-page fee to do it over the internet. A lot of times a hard-copy fax to a business gets more attention than an email. There's no delete button on a hard copy fax like there is on an email.
You can send a fax for free from www.faxzero.com. I usually type the letter as a word document and then use the service to send it in.
Just another tool for your kit to further the cause.
