Not all events require permanent pages on a website. iSite has a News module that will keep parents informed of planned activity within the school while building an archive. 

News can be grouped by category so related articles can be displayed together. And they can be tagged with key words so that articles with a lose association can be viewed together. And all articles from the same author can also be viewed together. As can be seen in the right-hand column.

Categories can be set so that only registered users with the correct level of access can seethe article.
