To anyone who wants to submit a review for 2009:
I think there is an automatic date change in the system which switched to 2010 right on schedule, but someone forgot to tell it that members still need to post reviews from the last few months of 2009.
Until it's fixed please choose January 2010 as the date, but at the beginning of the text state what month that you were actually there in 2009. The review checkers have the ability to correct the date back to 2009. They are already aware of the problem and know to watch for it.
Sorry for the trouble, and hopefully this will be corrected soon.
