Google Docs Google Groups Catch the Real – Webmonkey
Previously, sharing Google Docs and Calendars was limited to two basic options, the entire world (public docs) or individual e-mail addresses added by hand. But what about situations where you want to share a document with, say, several hundred people on a mailing list?
Provided your mailing list is through Google Groups, now you can do just that. The new Groups sharing feature adds an option to share Docs, Calendars and Sites with all the members of a Google Group. The group’s members can then simultaneously open and edit the same document, and everyone you’re sharing with will see the other parties’ edits appear as the doc updates every few seconds.
