There have been some questions about the “login” link on the new website (on the right side): This login is for the moment used only for administration of the website, so members do not need any user names of passwords, all content on the website can be seen by anyone without login.
The user names and passwords that some members have, were created for the old website for accessing the members-only discussion boards. These discussion boards were later removed and also the login for the website was removed. Later a new website was created, so the old user names and passwords will not work here even in the future, you can forget them!
