I have been using word web for quiet some time. Today i just opened it like i regularly do, it popped up a windows asking me how many times have i travelled via airplane in last year. I thought it would be some captcha type thingee trying to make sure that im not a bot or something. So i clicked randomly on one of the given options (I don't even remember what it was ) and guess what, I can't use the software any longer after it gave me this message..
So one tip.. Always read the licensing terms before using the software
