A while ago I read a Facebook status from an acquaintance that mentioned a "secret folder" in Facebook's messaging system. The status advised all readers to immediately check this folder for important unread messages, and I remember rolling my eyes and thinking something along the lines of yeah, RIGHT. It sounded an awful lot like those chain-lettery panic-statuses that tell users to click 17 different things to prevent Facebook from rifling through your underwear drawer, or whatever.
Despite my skepticism, I did go ahead and check this mysterious folder, and lo and behold, I had three missed personal emails. One was a greeting from a friend I hadn't seen in nearly two decades -- and his message had been sitting there, unread and ignored, for seven months.
As it turns out, that Facebook warning was no scam: if you haven't checked the Facebook message folder marked "Other" lately, you may be missing something important.
