I am running SilverStripe 2.4 and have just downloaded and installed (I think) the workflow module..but am not seeing the Roles section on the gray nav bar at the top of the CMS.
I downloaded cmsworkflow-v1.0-rc4.tar.gz from http://www.silverstripe.org/cms-workflow-module/, unzipped it etc., moved the resulting folder (cmsworkflow-v1.0-rc4) into my installation as a peer of /cms, /mysite, /sapphire, /themes, etc., renamed the folder simply "cmsworkflow", and ran a /dev/build. Everything seemed to go as expected.
When I'm in the CMS, I do see the workflow options added to the Site Reports section.
However, I'm not seeing the Roles link on the top (dark gray) navigation bar. Has the location of this link changed since the documentation was last updated 2 November 2009? Or perhaps I missed a step somewhere along the way?
