The game ends at midnight tonight, Pacific Daylight Time. The rules for this game say that, "Any Private Message marked with a date later than midnight, Pacific Daylight Time, of March 24, 2008 will not be considered." If you want to know exactly what time your PM will be sent, click on My Stuff, My Preferences and scroll down. Near the bottom, right above "Hide from Who's Online?" you will find a line that says, "Current server time is:" followed by the exact server time. It's that time that will be stamped on your PM.
