Major site functions like commenting, sending personal messages, and
uploading images require you to have a registered username.
This only requires you to pick a username and password.
You can optionally provide an email address so you can later reset your password
if forgotten or if someone needs to contact you.
Your username should contain only alphanumerics and underscores and be less than 20 characters in length.
Your password should be at least six (6) characters in length.
Your email address is used only for account validation should you need to reset your password.
You will not receive unsolicited commercial email nor will your email address be sold to any third parties.
