It seems the old username and PSSWD do not work in posting messages. I think there are two ways to overcome this problem:
1. Use your old Login name and Password to login, then logout. It seems you can post messages in the logout position. I have not tried it myself, but the Add Discussion button appeared. I have tried to ask the Administrator to give me a new Password by saying I forgot the Psswd, but I have not received any response. After that, my original PSSWD does not work.
2. Have to register a new name. That is what I did. You will receive email response immidiately, and then you can login in immidiately to post messages.
Good luck.
