From: Unknown User

    hi,
    i was working last night and didn't close the VM by svaing it on frozing
    state. now i cant log back again to the system by using my own username and
    pass. but i can login with Zope and other user name such as Yinjing or
    Cedric de Saint Martin, these works fine.
    what should i do?
    Thank You.

Just went back where we have to change user name. the guideline from moodle.
