Mailarchives (A83: Would like to unsubscribe)

I have been receiving lots of strange messages lately about TI-83 calculators. I was just visiting some TI sites looking for some fun games and I must have accidentaly subsribed to this mailing list. Could you please remove me from the list. Thank you. While I'm at it, could you tell me if there are any programs that would give me an answer from the quadratic equation in the proper form (a radical plus an integer over an integer). Also, what are my options for buying a computer-to-calculator cord. What are the prices like.
