I purchased a 200Gb. subscription plan for Google Drive, with the idea that we could use it to share files in an event we are organising. The problem is that many of the people who upload files to our Drive only have the free version (with its 15 Gb. quota)... and when they start uploading files, they eat at their quota instead of our 200Gb.
I've been searching and this seems to be how Google Drive was designed, but it's a big problem for our use case. Google's "family plan" (or however they call it) allows only 5 people to form part of a group and share drive space, and this is too few for us. Are there any other solutions, Google products, workarounds...?
