Good question Laurie. We used to allow 'guest' comments - i.e. comments without the need for logging in but after a legal case (nothing to do with us) in which a website was found liable for some libellous comments it hosted on the basis that they were provided anonymously, we had to tighten things up a bit to make sure that we didn't fall to a similar fate. You can still quickly and easily register an account with Discuss - the company that provide our comments boards. That way your Facebook and Google accounts won't enter the equation.
