For the information of my non-Namban readers, my friend Gareth started a group blog for the use of all the Namban Rengo runners (all 52 of them) to use as we approach Tokyo. He publicized the login and p/word to our mailing list. Though if that's how people post they have to be sure to sign their name to posts. Those with blogger accounts (like moi) could, however, set themselves up as contributers, so our posts (and of course comments) show up with our blogger identity. It hasn't quite taken off like wildfire, but is an interesting experiment and has certainly had a reasonable amount of activity. If you have time to kill or enjoy distractions, you may wish to have a browse of...Tokyo and Beyond.
Maybe some time you too will feel the need for a group blog.
