Registration
How to get an account: registering, the waiting list while the registration is full, and the terms of use.
Registering
On the login page, Don't have an account? Register opens the form: a username, your email address, a password and the answer to a small sum. Confirm the address with the mailed link within 24 hours, otherwise the account is deleted. While the registration is closed, an invitation code is needed (a link with a code fills it in).
Waiting list
While the registration is full, Join the waiting list on the register page takes your email address and the username you want; the name is reserved for you from then on. Confirm the address with the mailed link: the same link later shows your place on the list and lets you leave it, which deletes everything. As soon as there's a place, you get an email with a link to set your password (valid for 7 days, afterwards use "Forgot password?"); it logs you in.
Terms of use
Registering, like joining the waiting list, accepts the terms of use shown (the box below the form; the terms are linked there and in the footer). When they change, PaSiCC asks you after logging in: before the new version applies you can accept it right away or later; from the day it applies you can only accept it, export your data, delete your account or log out.
