I understand that Lost In Space has used many exclamation marks.But he has also specified that the answer is a free man . Does this clue match with your answer?
Yes - I am not a number, the i upside down, the exclamation marks all over the place.
could have made this harder - try the one i first posted Unsolved. still not answered with correct solution (that i am looking for, which is a debateable answer - just needs more thought)
