I've just gotten the "The server is too busy" message--or else the site timed out while I was trying to sign in and simply did nothing past the point where I enter my ID and password. That time-out thing has sometimes has even happened when I've been online and the site has "locked up," usually for about three hours. I won't allow me to sign out or navigate between forums. I assume it's been when work has been occurring. I just leave the computer and come back and sign off later when the site is accessible and navigable again.
