They are using Confluence by Atlassian (makers of JIRA). I have also looked at Confluence which seems like a nice tool and it seems to have worked well for this presenter for an Intranet environment. For a wiki this is the solution I would look at when regarding the need for a simplified tool for the staff and faculty I need to consider.

They had considered other solutions like MediaWiki and Drupal. Confluence was implemented because the IT staff already was providing support for Confluence.

I would like a tool that expands beyond the tools that Confluence provides and am now looking at a solution that provides a wiki solution in combination with blog and social aspects as well. I’ll write separately of that investigation.
