(You can also find them simply by searching for the word "Enigma" on our site.)
The rest...is up to you. :)
I think that the people who have solved the Enigma were sharing clues and insights and came up with the answer through interaction with each other. Sometimes sharing helps.
I will post a complete answer in early April, here on the website, detailing every clue, its significance, and basically more than you would ever want to know about the puzzle and its solution. :)
Good luck!
