Open Source Document Management System | OpenKM

Hi all
I installed OpenKM 5.1.10 community editon , i tried to stamp a document but i didn't find the stamp icon , which i saw in the online demo version.

Thanks alot.

In online demo is professional version 6.0.0 with extensions. On community extensions are not available but you can build your own if you want. Take a look here http://wiki.openkm.com/index.php/Extension_Guide and here http://wiki.openkm.com/index.php/Developer_Guide
