Paper presented at SOLSTICE 2007 Conference, Edge Hill University. Abstract: Wikis have been heralded as one of a number of new and powerful forms of software capable of supporting a range of collaborative ventures and learning activities. The Sakai wiki tool, implemented by CARET, was originally designed to support participants in collaborative research projects. We immediately saw an opportunity to use the wiki tool to structure the content of the IB PMS course site within our Sakai based Virtual Learning Environment (VLE). This enabled the site to contain searchable wiki formatted lecture notes with links to glossary pages and to a wide range of other learning resources. However, we initially restricted the access and editing rights of the site members so that lecturers have edit but not administration rights and students are unable to edit any pages. Are we breaking the rules? We put across our case that the wiki is a more versatile tool than the developers originally envisaged, and that it is not necessary to allow full editing rights to all members of a VLE in order to support the teaching and learning of students in higher education.
