Select a group type
Different groups can serve different purposes and have different workflows. For example, an email list group is a group where all of the communication takes place using email (common in many businesses), whereas a Web forum allows communication using both email and the Google Groups user interface.
Group types formalize how you will use Google Groups by automatically configuring settings to match a common workflow. For example, by selecting the "Email list" Group type you are effectively turning off the "Allow users to post to the group on the web" permission and denying members the ability to use the Google Groups user interface. Following is a description of the standard group types:
An Email list group is one whereby members only use Email to communicate. This group type is common in organizations where a single email alias is desired to communicate to a certain group of people using email.
A Web forum group is one whereby members only use the Google Groups user interface to communicate with other members. This group type is similar to the online web forums found on many web sites.
A Question and Answer (Q&A) forum group is one whereby members use the Google Groups user interface to primarily answer the questions of other members. This group type is similar to the online product forum.
A collaborative inbox allows members of a group to manage the workflow state of topics within the group. These groups have specific features and permissions set. If you choose to not use these features, they will need to be disabled individually.
