I'm sure every other blog and web site has a link to donate for Katrina disaster relief but in case you have missed them here is ours.
Give what you can. If nothing else how about skipping a week's worth of coffee or music purchases and giving it to people who may have lost absolutely everything?
Update: I'm going to keep this link at the top of the blog for a while so it doesn't get buried. If anyone has suggestions for other relief agencies that should be listed please let us know. Updating a blog seems a pretty inconsequential thing but from this distance that and sending a check is about all I can think to do.
