Nico, the answers to all of your questions can be found by taking a few moments to navigate the different areas of the website.
You are not required to enter more than one nickname when registering (which you must have noticed since you filled out the form).
You should now have the confirmation email and you are should be able to access the passwords section.
Our passwords are given out shortly before each game and that's why you only saw one person registered. None of our games are at risk of being canceled with this method.
Please let me know if you have any other questions.
Thanks,
NDN
