As more and more businesses and organizations "go Google," we find that many of the features we develop based on feedback from large enterprises end up benefiting all of our users. We recently rolled out improvements to the way Google Groups interacts with several of our applications. Now, sharing calendars, sites and documents with multiple people is easy — instead of adding people one at a time, you can simply share with an entire Google Group.
As an example, imagine you're organizing a local intramural softball team tournament. You use Google Docs to keep track of the rosters for each team as well as each team's performance.
You want all the players, but only the players, to have editing access. You already have a Google Group set up with the tournament participants, so you simply share the spreadsheet with the group itself, granting the group members permission to edit.
Now, when people join or leave the Google Group, they will automatically gain or lose editing access to the spreadsheet. It's that easy.
This was a feature that people wanted to "just work" — and now it does. Go ahead and try it out with your sites, calendars and documents!
