The site http://tex.stackexchange.com is now open to the public. Anyone can register there and read, ask or answer questions related to TeX. Like on the popular site Stack Overflow, the audience votes for good answers, so the best answers are easy to find: at the top of all answers.
The status of the site is now public beta. This will last from 60 to 90 days, afterwards we’ll see if the site is successful and would stay online.
Now, after 7 days in private beta, the site has 323 users and 658 answers to 242 questions.
