In a 72-hour media blitz that kicked off Monday, Web wanderers can view photos, bulletins, and information about the mother, who has been missing for nearly a month, on Facebook's Friends and Family of Susan Powell site.
A slideshow of photos of Powell, 28, as a child and adult, can be viewed on YouTube. Send an e-mail to findsusanpowell@gmail.com to get instructions on how to distribute e-mails to help find Powell. There is also a campaign to make Powell a top-10 topic on Twitter.
"We believe that by spreading the information as far as we can, we certainly increase our chances of hearing from someone who might remember something or might have seen something," family spokeswoman Shelby Gifford tells PEOPLE. "There's no way that I personally can hang a flyer in Australia right now, but using the electronic means that are available to us, we're able to reach all of those corners."
She adds, "The unexpected side effect for the family is we're able to get on the Facebook site 24 hours a day and be comforted and soothed by the words of support. We appreciate them all and we read them all."
Powell disappeared from her home in the Salt Lake City suburb of West Valley City around the night of Dec. 6. Her husband, Joshua Powell, tells police he took the couple's young sons on an overnight camping trip – on a night police note was extremely cold – and when they returned the following afternoon, Susan was gone.
West Valley City police say they still consider the matter a missing persons case, and Joshua Powell a person of interest.
