In the very unlikely case that for some reason I have your IP address, there could be a message for you in the yellow box on the right of this page.
It's just a silly experiment: I was watching the logfile of my weblog's server, and I saw a known IP address passing by. "It would be cool to be able to leave a message to this person" I thought. Well, now I can, simply dropping a .txt file with the message into my Radio/www folder.
Of course, it could be better implemented using cookies, a Radio tool could manage subscriptions, there could be other features... who knows, maybe this might a new tool (after we will finish the ones we are currently working on!).
