As you've seen from the most excellent Ben Finn below, we've migrated the server over to the new host, but with some problems. Specifically, the Premium content pages and the forums aren't letting people log in.
Ben (and I, but mostly Ben) is working assiduously to figure out what the bug is. I apologize for the inconvenience and frustration, but hopefully things'll be squared away soon. In the meantime, the apps all still work so you can continue to create away.
A big THANK YOU to Ben for handling all this, too!
