Keeping of track of guests and the distribution of specific roles over the guests. In our example cooks & instructors. You type the name of the person and you confirm the presence or add a new person. The roles available are linked to a table telling how many you need.
Everybody who once had to deal with keeping track of volunteers or a technical team may benefit from this.
I explain conceptual relevant steps to help you to understand faster how this works. In case you just want to use this doc as an instrument to keep track of your guests without playing (a bit) with the code, you can.
