I've been chatting with visitors on my site for a while. Most of them want to sign up so they can interact with the forum and blog (Which work GREAT!), but they don't want to give out any personal information. As of now, I'm only telling them to use disposable email addresses. I know they don't want to share that kind of info, and it's their right whether or not they share that kind of info. Could there possibly be signup only needing a Username and password? This would probably make my site's membership levels go up.
