I've done it too. Sometimes the edit and reply buttons are too much alike.
I recall bets being placed on how many spelling errors would be found in the daily cruise programs from Carnival, Royal Caribbean, HAL, NCL, etc. What bothered me is they didn't seem to have boilerplate print for items that never changed week-to-week, yet you'd see a word spelled correctly one day, but the following day the same word would get butchered. My example was "St. Maartin" which blended both the French and Dutch spellings, yet they managed to get the Captain's difficult name of Eelko Yytmaa correct every time. This was with Holland America on the old Westerdam. The apparent reason is assigning crew who are not fluent in English to put together the Cruise Compass, Princess Patter, etc. Not a good idea for cruises embarking in U.S. ports with a mostly American audience.
