[boost] Mailing list archive change and list downtime

DongInn Kim, Jeff Squyres, and the other sysadmins at Indiana University are planning to switch all the Boost mailing list archives they host from MHonArc to Hypermail. They report "Hypermail seems to be much more stable, faster, and more efficient than MHonArc. We've been quite pleased with it, and have deployed it across most other lists on the listserver already (the boost lists were saved until last)." The old archives will still be available, and DongInn and Jeff have made various plans to minimize disruptions. All the listservers will be down during the transition, which is planned to start at 11 PM Saturday night (Eastern US time). Thanks to all the folks at IU for their help with Boost list hosting, --Beman
