Not relevant to ECC, but if anyone here has spare time and any interest at all in crypto, please contribute to the linked site (http://crypto.stackexchange.com)! In case anyone doesn't know, StackExchange is a network of Q&A websites, of which StackOverflow was the first. Sites go through a proposal process and, if enough people commit, a private and then public beta. The Cryptography StackExchange site is currently in public beta. If it reaches a critical mass, then it will graduate and become fully-fledged member of the SE network.

As it is, the site is doing relatively well but daily activity is low (too few questions, too few visitors). But there are lots of knowledgeable people on it, and crypto is one of those areas everyone seems interested in, so the only real thing holding it back is a critical mass of good, active users. For many professions here on HN, it's useful to have a bit of crypto knowledge, so this post is a shameless plug. :)

You don't have to be an expert to contribute. In fact, one of the problem areas is a lack of good, well-researched, quality questions. Of course, any new expert is welcome too.
