As previously announced, we will be raising the visibility of version 2 of the NB platform by hosting it at the main
nb.mit.edu site instead of its previous
nb2.csail.mit.edu . We have begun this switchover: the original version of NB can now be found at
http://nb1.mit.edu/ . We plan to host it there indefinitely; you need not fear losing any data.
Anyone who plans to stick with version 1 should shift all their links to the
nb1.mit.edu site as soon as possible. For the next few days, version 1 will also be available at the main
nb.mit.edu site, but in a few days,
nb.mit.edu will be hosting version 2 instead.
