There exists a new website for mathematics:
http://math.stackexchange.com/
Users can post and answer questions about mathematics. Questions from all levels of mathematics are permitted and encouraged. The site is not a discussion forum; instead, through an efficient voting system, the site aims to obtain definitive answers.
A related site is MathOverflow. This site is an amazing tool used for mathematical research. Mathematicians ask and answer questions on the site, making communication in research much easier. The new Math.SE site is a more open relative of MathOverflow.
Math.SE was created through an open democratic process at Stack Exchange’s Area 51. The site entered private beta a week ago, and as of today, it is in public beta and everyone can use it. If you’re interested, go make an account. Spread the word and help this site succeed!
