After filling out the form you will need to check your email to get your password. You can then log in and will be given additional options to add urls (and in some cases, other kinds of information as well).
Username, Email, and Real
Name fields are required. Your username is the
name you will use to log in and will be displayed next to all of the
items that you add. This can be anything of your choosing, your email
username is a good choice, but you can use your full name if you like.
Be careful to enter your full email address correctly so that the
software can send you your password. Please enter just one email
address; if you have multiple addresses, choose just one to enter
here. Note too that your username and
password are case sensitive.
