I was feeling sorry for the guy that started that thread, so I took this discussion off to a new thread. I don't know if there is a better forum for it. Actually, I was already not using GUIs long before there even were GUIs. I got the miktex package and started using the pdftex utility. I haven't read any documentation so I'm probably not using it to best advantage, but it does work for me. What is the difference between tex and latex? Should I use pdftex or pfdlatex? Pretty soon I am going to post my results in Snyder-Conway theory on my website and it will be in a pdf file.
