John Mandia threw down a cool challenge idea...how to make Google search multiple sites at one time for a specific term.  I messed around with it for a while, and came up with this: 

http://www.google.com/search?hl=en&lr=&ie=UTF-8&safe=off&as_qdr=all&q=bowen+john+%7Bsite%3Agobowen.com+OR+rainbowportal.net%7D

Basically, from the Google interface, use the following format:

bowen john {site:gobowen.com OR rainbowportal.net}

...Where 'bowen' and 'john' are the terms to search for, and 'gobowen.com' and 'rainbowportal.net' are the two sites I want searched.  Neato! (though admittedly, this example is a bit conceited)

[edit]After posting this, I went back and read the comment from Clint S. on John's site - it looks like the curly brackets aren't needed for single-term searches, but for multiple terms, you have to have them[/edit]
