Proposed by: Allen Liu
Answer: 258
There was one problem for which I could not determine author information, so I set the author asone of the problem czars at random. Then, I ran the following command on a folder containing Te xsolutions files to all four contests:
evan@Arch mega ~/Downloads/November
$ grep --no-filename "Proposed by: " *.tex | sort | uniq -c
15 {\em Proposed by: Allen Liu }
1 {\em Proposed by: Brice Huang }
2 {\em Proposed by: Christopher Shao }

21 {\em Proposed by: Eshaan Nichani }

3 {\em Proposed by: Saranesh Prembabu }
3 {\em Proposed by: Shyam Narayanan }
This gave the counts of problem proposals; there were 14 distinct authors of problems for November - Summing their ages (concealed for privacy) gives 258.
