Hello.
The forum format changed recently. Some people have had to register for the new and improved format that had never done so for the Events and Chapters forum.
The process is pretty simple, and we have been trying to leave a reminder notice on the old (archived) forums every couple days.
The two authentications systems have NEVER been able to talk to one another. Using a standard format for all of the forums will cut down on the high maintenance of password problems. Once the Members forum is moved, people will need only one login as opposed to the three we used to have.
That is it in a nutshell. We do have a Support area, and encourage folks to post problems/questions there to ease in tracking.
