I love HelloFax. Really, I do. Started using it a few weeks ago, and discovered undocumented features that were EXACTLY what I wanted. Before when I ran a web dev company I had to sign contracts all the time, and this was my process: save from email -> word -> enter text / insert image (signature) -> print to pdf -> efax. Now I can do it via HelloFax in about 1 minute.
+1 We got a chance to use HelloFax very early on, and we never actually sent any taxes - we were using it to sign documents: vastly superior to my old way of scan&convert to PNG, open in Gimp, paste my signature, merge layers, convert to PDF... Ughh. So it's not just about faxing.
I second that. HelloFax makes what used to be a huge pain really easy. I've tried other options in the past (borrowing someone's fax, other clunky e-fax systems, or a trip to Kinko's) and I'm happy I'll never have to do it again.
