Access to solutions of other users is temporarily blocked is an infuriating message, because of the lack of a time limit. When the powers that be decide that the mission will be unblocked, there appear a timer for the unblocking; such a timer ought to be provided from the get go. Further, keeping the board blocked for more than a week (ok, maybe two) is quite disrespectful of the participants. I, for one, like to see other solutions - I learn from many of them; I surmise others also feel the same.
