Open Source Document Management System | OpenKM

Hi all,

I am new to the OpenKM community edition. I have followed various guides and have the installation working well on a Linux server. When I logged into the demo version of OPenKM located on the main website I noticed there is an icon for "wiki". On my installed version I do not have any such icon. How can I implement this?

Wiki is extension only available in professional edition.
