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 (2603:A041:23FA:0:1CD9:1493:8DCC:601A) 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 [//en.wikipedia.org/w/index.php?title=User_talk:4thfile4thrank&action=edit&section=new my talk page], or ask your question and then place  before the question on this page.
