The old board simply was no longer adequate to our needs. Hopefully, this board, which gives us the ability to better organize and moderate discussions, will be more flexible and efficient.
Due to the large number of new posters, we have also decided to require email registration in order to post. This will allow us greater control, and benefits users as well; registered members receive the ability to upload avatars, subscribe to threads, append signatures, hold private messages, etc.
There will be a learning curve involved for all of us but we can figure it out.
In the meantime the old board will remain open so that discussions there may be restarted here.
UPDATE 04/24/06: The lease on our old board expired and it is now history.
