You are welcome to continue editing without logging in, but many editors recommend that you  [ create an account] . Doing so is free, requires no personal information, and provides several benefits, such as the ability to create articles. For a full outline and explanation of the benefits that come with creating an account, please see this page. If you edit without a username, your IP address (143.107.220.119) is used to identify you instead.

In any case, I hope you enjoy editing here and being a Wikipedian! Please sign your comments on talk pages using four tildes ( ~ ); this will automatically produce your IP address (or username if you're logged in) and the date. If you need help, check out Questions, ask me on my talk page, or ask your question and then place  before the question on this page.
