Finally Google has made this simple and logical move - Google Groups have been added to its online suite of business applications. Google Groups allow you to create workspaces for departments or projects that include wiki, discussions and files. And also Google Groups allow you to quickly provide access to the various elements in Google Apps (documents, calendars, videos, sites) to certain group of employees. And when the user is excluded from the group, he loses access to all the associated resources. Groups in Google Apps can be created either by the administrator or users themselves, if the administrator has allowed this. The group owner set up access rules, public access options, invites participants and moderate their actions.
The bad news is that Google Groups are only available in paid Premier and Education versions. Besides, though Google Groups are now officially business-ready, Google hasn't corrected some unpleasant bugs. For example: - Horrible support for pictures in Pages - Restrictions on the comment size - Outdated format of discussions - mailing lists - No folders in Files section
