Just fyi, tilfo: maybe I'm paranoid, but I haven't signed up to participate because I just don't like the idea of having to send in my e-mail first. If I could just click onto the site, I'd feel much more comfortable. Something akin to why I refuse to register with certain newspapers in order to read them on-line, maybe. I think it's more to do with the feeling that, once I've sent my e-mail address, it will no longer be my choice whether to paricipate or not. Just my 2¢.
