Respectfully, if someone wants to leave, they usually just do it. They don't make a new thread about their departure, and they don't check back in to discuss things further.
That said, I see this thread as a cry for help, asking where did all the good times go? The golden era of AZ.
Please understand that this is a pubic MB, and I love the fact that there are so many knowledgeable, passionate posters.
Don't let some fool who posts obscene pic files around here, or acts rude or obnoxious take away for the relationships that many have formed here. That would be a loss to the individual who left, and to people like me who could benefit from someone who is knowledgeable and enthusiastic about pool.
