Ppl are retweeting this and I just want to add that faxing is THE most annoying thing to do to your representatives. There are websites where you can fax for a small fee and those machines are LOUD and then at the very least they have to deal with all the print outs.
If you're old laptop has a modem, it can probably fax. In Windows it shows up as a printer. You can even specify a cover page! A ridiculous cover page will double the amount of annoyance.
