This is an excellent idea thought up by Chris and Max. Register, create a summer themed music CD and send it off to five other webloggers. It appears that it is only open to Americans and Canadians. I emailed Chris and asked about the Canadian thing and he said that there are probably enough Canadians for this to work but he was going to ask the people who are currently registered whether they mind a little extra postage.
If you sign up you might be one of the lucky 5 who get a summer themed CD from me. I will have to start working on it soon. It usually takes me a couple of weeks to make up a good mix CD.
