I got a letter a month or 2 after I left (middle of 2006) and just got another the other day. Didn't sign for the certified letter. Sounds like a mass mailing in an attempt to get any money they can. There must be literally hundreds of us out there who left before one year, and if they can get just one of us to pay up, it'll pay for the cost of all those letters and then some. I don't plan on responding, or paying. I'd rather pay a lawyer twice the amout Mesa thinks I owe them then give any more money to JO and his entourage of liars.
