I lost my Password? What can I do?
Go on this link and write your username or mail address in. Then, you get a new password by mail.
But if you wrote your wrong mail address in a registration list, you naturally can’t get a new password!
Then contact your teacher or school coordiantor.

What is my username?
surname.prename.s
s=student, al=alumnus, t=teacher or sc=school coordinator
Attention: If your name includes some special character (like “ä” or “ł” etc.), it will be changed! Then, ask your teacher for the right one.
