| # * index - shows a list of WikiPages grouped by page or date | ||||
| # * new - not used | ||||
| # * create - not used | ||||
| # * show - will also show the form for creating a new wiki page | ||||
| # * edit - used to edit an existing or new page | ||||
| # * update - used to save a wiki page update to the database, including new pages | ||||
| # * destroy - normal | ||||
| # | ||||
| # Other member and collection methods are also used | ||||
