Dare posts about two charity search sites hosted by Live Search. Use teamseattle.live.com to search and you help sponsor Children's Hospital. Use click4thecause.live.com to search and you help sponsor Ninemillion.org, which is working to help the 9 million refugee children worldwide.
GIven that I'm already using Live Search, changing my default search page from Live.com to one of these two seems was a no brainer. I use the IE7 Search Box more often than not, so I also set up a custom search provider. However, that's a bit of a PITA, so I took the OpenSearch Description XML files and hosted them here @ DevHawk. Click the links below to add them to IE7 search box.
I'm sure there's a way to do this for Firefox's search bar, but I have no idea how. If you - dear reader - know how to add search providers, please send me email and I'll update this post accordingly.
