Lol yes that is an unfortunate overlap of terminology. Maybe I should have avoided using it. Prior to Dropbox(TM) we'd refer to a network folder shared for the purpose of letting others upload to, a drop box. MacOS used this, with ~/Public for sharing files out, and ~/Public/Drop Box for sharing in.
What I ultimately seek is a way to flag a specific folder within a share as write only. I assumed the Dropbox docker was just for linking to your Drobox(TM) account, but I will check it out, thanks.
