forum upgrade

Forum mods have been working to improve the new forum and plan on upgrading the forum to phpBB3 on tuesday evening UTC (about 1800).  They will need to take the forum down for a couple of hours to do this, to make sure that a) we don’t loose anything, b) that they don’t break anything.

While the upgrade is in progress, they”ll set up a redirect that gives an info message with a link pointing people to the google group so people know what’s going on.
