Sprint Relay Online (SRO) is a service offered to deaf and hard of hearing individuals that allows them to place relay calls over the Internet between locations in the United States. It is free, easy, and only requires a computer with internet access. Try it out by calling yourself. You will be acting as both parties in the conversation that is interpreted by a Sprint operator. When you begin running out of things to say to yourself, the phone call becomes awkward. If you decide to phone a friend and type something inappropriate, or aggressive, the operator will translate this to the listener. I can see many uses for a service like this, especially since it is free.
