I would like to know if there is a simple way to enter mathematical formulas in PF. Someone suggested a few days ago that I use WinShell. This doesn't seem to be easy to use and the documentation is not very helpful. I thought for a while that I could eventually use it to write articles, but I am getting frustrated. Even If I can't find a good, well documented program to write LaTex articles, I would like to have a way to insert mathematical expressions in the forum. I though the forum used to have a built-in way to do this a few years ago, but I don't see that now. I realize that I can learn LaTex and type it in, but I would rather use my brain to learn more physics rather than LaTex. If there was some WYSIWYG program similar to Equation Editor which allowed to save the formulas in LaTex that would be great. I'll appreciate your help.
