Database User Registration
Registration for permission to submit Database entries is easy and free. You must choose a user ID and password, and register a real email address. The email address is so that editors can get in touch with you with questions or instructions. The email address is used during registration, so it must be valid.
If at some later point an attempt is made to contact you and the email address doesn't work or you don't respond, your registration will be suspended. So don't make it a throwaway account. Don't try to register more than once with the same email address.
To prevent selecting a user ID belonging to someone else, you can use your email address as user ID as well, but it's not required.
