I also just made silver, and it was great to be able to use the Business counter to checkin a bag (which I rarely have, so won't be able to do this much!) when the queues at the quick drop were looong. (As an aside, the internet checkin bag drop- always empty! Shorter queues than Business, if you did the 'net checkin/printout).
Anyway, it went alright, except for the fact I was getting a bit confused from all the recent travel:
(MEL checkin): Where are you travelling today?
(me): Melbourne!
(MEL checkin): Sir, you're in Melbourne. Which flight are you on?
(me): uh... hmmm....
apparently it happens more than you might think...
