If people are in the apology mode - I'll confess that it was me who caused the 'guest' prefix to be invoked.
I've used a number of aliases during my time at mudcat, and I've spent most of the time offering good advice. Occasionally I get frustrated, and post overtly provocative threads - the 'americans are fat' was me too.
I'm using a different name now, and I often still answer 'guest' requests that no-one else does, and spend a good deal of time on search engines picking out obscure information for people that I don't know.
Judge me as you will
and please stop blaming the semi-mythical gargoyle for everything
