A Microsoft file hosting and synchronization service.
gogooglego, I do not share your enthusiasm for Google Workspace, or Google anything for that matter, other than the search engine. It's not that they are bad products, but rather that the documentation, such as it is, is so poor. I am trying to create a space for a community organization where documents and other files can be shared. This is not a possibility Google has anticipated, apparently. The Google Workspace site is geared toward using it as a full-time collaborative tool at work. If there are other possibilities, they are buried deep in the jargon.
Then there is Google Groups and Google Drive, which may or may not be part of Workspace. One thing for sure is that we aren't going to have lengthy training sessions just so people can occasionally refer to a membership spreadsheet or revise the guidelines.
I'm not a neophyte. I made my living as a database developer and technical writer. I know how to write instructions. Google's instructions are dreadful.
