A group admin can create a group wiki and corresponding group wiki pages. Each page has settings (which can override the group privacy settings) to control access to the page both in terms of view access and edit access. The group also has a shared document library for uploading files. Page revisions are fully supported, as are revision compares and restores. Activity stream updates for wiki edits are also created, based on an excerpt of the changed text.
