"Thanks for visiting TPCint.org. I decided to keep the spirit of TPC.int alive by creating this informational site, since I was able to find only one person still involved with it. Happy free faxing..."

The Internet Multicasting Service, TPC.int, is a non-profit organization that operates a free e-mail-to-fax service. They rely on volunteers from the U.S., Australia, Canada, Denmark, Germany, Greece, Hong Kong, South Korea, New Zealand, Portugal, Sweden, Taiwan, and the United Kingdom, who maintain fax servers in their particular areas, so all phone calls to fax machines are local.
To send a fax using TPC.int to someone, first create the e-mail message. Then use the following address, replacing the italicized variables with the actual person's name and phone number, but keeping the punctuation (including the underline) intact:
remote-printer.First_Last@13135551234.iddd.tpc.int
Note that the phone number is one continuous string of numbers, and it must include the 1 and the area code, even if the fax is just being sent across town. The service automatically sends you an e-mail confirmation either stating that the fax transmission was successful or did not go through because there is no local fax server in that area.
