Finding people on the Internet

[grbh]

I'm trying to track down a friend who has moved, switched jobs, and I've misplaced her number. Evidently she is unlisted, because I can't find her on switchboard, or any of the other phone listing sights. I've googled her, but to no avail.

The only place I think I've found her is on USsearch.com, but it is going to cost me $20 to get the info which I'm not 100% certain is what I am looking for.

So my question is are there any sights similar to ussearch I might be able to use to track someone down.

Thanks for the help.
