I noticed you are known only as an IP address; that means you are not signed up. To sign up, you only need to click Create account and choose a username and password. You don't need to provide any personal information. If you sign up, you'll have a username that others can use to recognize you and leave you messages on the wiki. You'll be able to sign your name just by typing four tildes, like this ~~~~ when you leave someone else a message. Plus, you (and others) will easily be able to see a list of all your contributions to Wikipedia.
This is the discussion page for an IP user, identified by the user's IP address. Some IP addresses change periodically, and may be shared by several users. If you are an IP user, you may create an account or log in to avoid future confusion with other IP users. Registering also hides your IP address.
