As George himself pointed out recently, Customer Service is not reading the boards. They're not SUPPOSED to be reading the boards. They're processing your support tickets.
Your ticket number is something to keep between YOU and customer service, not you and the Chat board. There is NO reason to post a ticket number on the board. All that could possibly do is give someone a chance to screw around and interfere with solving your problem.
Anyone who tells you to POST about a customer support issue is part of the problem, good intentions not withstanding.
