ThemeDoctor.com - safe wallpapers and desktop themes
review from ClifNotes, Nov 2006, permalink _ Cool Website
There really aren't too many safe places to get free wallpapers, themes, and screensavers. This site has my approval so far. The single exception I'll mention is that they have advertising links to some very risky websites. In other words, don't click on the ads.
I think this site should have a "yellow" rating at SiteAdvisor and ScanDoo. It's green right now.
