Hmmm... Maybe it was just me, but I couldn't get to the board or the members page because my logon was suddenly invalid.
Maybe they're getting the members page ready for pontifex II....

It happens to me nearly every time, I just put my details in again and it worked. More likely due to heavy internet traffic than construction on the site.
