Registration is not required to participate on most Stack Exchange sites; you can read, answer, and suggest edits as an anonymous user, much like on Wikipedia. There are some things you won’t be able to do on the site without registering, however, such as vote. Registering is easy, and once logged in, you can gain other key privileges by earning reputation.

If you have a registered account on any other sites in our network with at least 200 reputation, you will receive a +100 point reputation bonus when you first log in.
