  WHY would I want your door?  I've got better things to do with my time.  It's not like I don't understand things like formatting, because I do.  I am the author of the first ever publicly released Elisa program, written at the University of Wisconsin back in the 80's.  I was published by the University of Chicago press as an undergraduate.  What is an Elisa program?  Surely a super user like you doesn't need an explanation, but I'll waste your time anyhow.  Bot's are the modern off shoots of Elisa programs.  Just 4 inches up the page it says Autosigned by SineBot, a Bot.  And it shouldn't be SineBot, unless it's a trigonometry bot, is should be Signbot.
