Here are some other hints and tips:
 * I recommend that you get a username. You do not have to log in to read or edit articles on Wikipedia, but  [ creating an account]  is quick, free and non-intrusive, requires no personal information, and there are many benefits of having a username. (If you edit without a username, your IP address is used to identify you instead.)
 * When using talk pages, please sign your name at the end of your messages by typing four tildes ( ~ ). This will automatically produce your username (or IP address) and the date.

I hope you enjoy editing here and being a Wikipedian! If you need help, check out Questions, ask me on my talk page, or type  here on  talk page and someone will show up shortly to answer your questions. Again, welcome! David Brooks (talk) 23:42, 17 March 2020 (UTC)
