Hello, i'd like to invite you to a new web site where i took part in building.
It's name is +Z puzzle, is like Project Euler but there are Puzzles instead of Math problems, I think most of the users of Project Euler would like +Z puzzle too, there are interesting features, statistics, contests, etc. If you have any suggestion about the site, please let me know.
