Please Feed the Nerds -- Macworld Expo attendees may wish to check out BMUG's free rent-a-nerd service. You can participate as either a nerd or as a user seeking assistance. "Rented" nerds provide guidance for dealing with the hype and confusion inherent in an Expo the size of a European principality, and they may accompany users out on the show floor. Nerds mainly earn gratitude, but pizza is also considered appropriate payment. To find out more, visit the User Group Room in Moscone's North Hall, Room 121. [TJE]
Single Time Machine Backups
Tired of Time Machine running all the time? You can turn it off in the Time Machine preference pane, but still initiate a single backup by choosing Back Up Now from Time Machine's menu bar icon. Of course, your backup is much less likely to be up to date, but Time Machine won't be taking any resources while you're trying to work.
