These groups can be used to define fine grained TWikiAccessControl in TWiki:

• TWikiAdminGroup
• EngineeringGroup?
• SupportGroup?

Add your groups to this list and define new group topics similar to existing ones. Group topics must end in ...Group.

IMPORTANT NOTE: Think twice before restricting write access to a web or a topic, because an open system where everybody can contribute is the essence of the WikiCulture. Experience shows that unrestricted write access works very well because:

• There is enough peer pressure to post only appropriate content.
• Content does not get lost because topics are under revision control.
• A topic revision can be undone by a member of the TWikiAdminGroup in case needed.
