GM4,
I agree with craz. Don't worry about Marriott. Just remain anonymous and periodically remind us that your opinions do not necessarily reflect the corporate line.
There are lots of employees of hotels, airlines and rental car agencies who regularly post on these forums in that same manner. As long as they are honest, their insights are usually very well received and add to the value of Flyertalk.
I hope you will be an active participant in this forum.
