Easy does it, amigo! Sorry to hear about your lost post, but don't go off half-cocked and ream the much-appreciated MercedesShop staff. Remember: these guys are giving us a free service, so the old addage about "Looking a gift horse in the mouth" applies in my opinion.
I too lost a post at one point, but oh well. If it weren't for the benefit I've reaped from the thousands of posts hosted on this formidable site, I'd have a considerably larger dent in my checking account from MBZ repairs.
Keep up the good work Bill
