Tuprnip Guest has gone on to coding posts in order to come up with statistics - very scientific. I don't think he's done much to (im)prove, or even clarify, his position.
Who are the Guests (plural) he is referring to? I have noticed that there are a number of Guests on threads with content who are happy to participate in Mudcat. They choose names to go along with "Guest" so we know it is not the determinedly anonmous poster who's unrelieved negativity has appartently made it necessary for him to go top extreme lengths to hide any hint of his identity. I don't see any sign that Guests are unwelcome, I think that aggessively rude people might find they are less apprecited than those Guests with something to add to Mudcat.
