Your username is what you will use to sign in to this website. You can make it anything you want, but you will need to remember it to sign in.
Your email is needed for things like password retrieval and will not be sold to anyone for the purposes of evil. There’s a slim chance that I might want to send an email that has something to do with your use of this website, but like I say, the chance is slim.
Please, user your actual real first and last name. If I ever needed to contact you, I don’t want to have to deal with “Lord Fuzzy Ears”. If you don’t want to use your real name on the website, that’s cool, you can set your Display Name to whatever you prefer in the account settings.
Make sure you choose a good strong password because there’s bad people in the world.
