If we place a master google drive project spreadsheet in a shared OSCEDays folder, participants can be given access to the spreadsheet, and the lead developers of a project can populate their projects, then any participants can join and participate in any of the projects by entering their name and checking off the project they would like to join.
If it’s designed properly, maybe people can just follow a standard format and append their columns or rows to the master spreadsheet and every week, the master spreadsheet can be resorted.
