How can I confirm that the format of the paper is correct?
The double blind refereeing instructions mean that the text of the paper should have nothing in the LaTeX    \author{} macro. All the authors should be listed only on the web form you fill out when you submit the paper.
For help setting the proper margins and other formatting constants, ask at tex.stackexchange.com.
Although you have never &quot;met&quot; your mentor, they should probably know about this submission and should be able to help you with it.
