PSA: I honestly did not realize that the folder was restricted on G-Drive until I opened my Gmail inbox and found a whole bunch of "request for access" notifications about the folder. I have now changed the folder's settings and e-mailed every single person back who requested access, to notify them of this.
If you tried to access the folder before but were unable, please try again - it should work now. If there are any issues with the folder (or anything on my G-Drive, really) please contact me. I'll be sure to be more on top of this going forward.
