Changes

:Once content is stored in WIKIs, '''it is amazing to discover how many times that content can be reused'''. For example, the Westminster Computer Lab resource [http://matrix.senecac.on.ca/~murray.saul/westminster/computerGuide_home.html /Guide on the Side/] has many tutorials that are recycled WIKIs that were created months or years ago... This web-page and You-tube videos were created from scratch within a 4 week period. There is no way that this resource could have been created by one person without these on-line tools (such as especially WIKIs).
