I've not been much worried about the whole Guest issue, but would point out that in the Sri Chimnoy thread, an example of the danger is shown. THere is a young lady in New York, who has paranoid fantacies about folks, and she made serrious and personal liabelous statements about me, who posts using my full name often (Larry Otway) and even my address - both email and snail mail when important. I think this is the real danger, mentaly unstable folks throwing barbs and running.
Cheers, Larry
PS I am not worried enough about it to ask for a change of format, but I would ask my friends to recognise that those of us who post truthful statements, sign them.
