I have been successful finding out how to make tables in PGML by searching "Table" on the webwork.maa.org site. But I have not had any success finding how to do something LaTeX-like such as making itemized list:
\item First thing
\item Second thing
Is there a place on webwork.maa.org where they "translate" how to do LaTeX-ish thing in PGML lingo?
Unfortunately, PGML is not well documented. I will be doing a session on it a week from Monday, and will go over many of the details. In the meantime, you can use this lab as a reference, as it includes examples of most of the formatting that you will need to do, and has menus that act as references for the various formatting rules.
For your particular case, simply do:
* First thing * second thingNote that PGML is based on Markdown, so you can use Markdown documentation os a guide for non-WeBWorK formatting, in general (though there are many flavors of Markdown, and not all extensions are included in PGML).
