<p>Before expo starts the folk.csv file is updated.
<p>Edit folk/folk.csv, adding the new year to the end of the header line, a new column, with just a comma (blank cell) for people who weren't there, a 1 for people who are there, and a -1 for people who are there but didn't go caving.
This is adding an extra column to every line in the file.
<p>
Add new lines for new people, with the right number of columns.
<p>This process is tedious and error-prone and ripe for improvement especially as expo proceeds and you have many more names to add. Adding a list of people from the bier book and their aliases (the name in brackets) would be a lot better, but some way to make sure that names match with previous years would be good.
<p>It is recommended that the nerd does this locally on their own laptop first. It does not need to be an expo laptop, even a Windows 10 laptop is fine if the script is run in a WSL terminal. The only software you need to install is the default python package.
