I have read about stapling at the manuals and info that have openkm but in any place is said that this characteristic is owned for some version specifically, so I suppose that in community version is posible to make use of it, however I havent found this option. could you give me some tip about it, please, thank you. Im using Openkm 6.3 with Linux Centos

This feature is still not present in community version. At end of year sure we will release in community version.
At the end you can see what is on professional and what on community http://wiki.openkm.com/index.php/User_Guide
Actually we're working hard on changing all documentation, we are conscious of the actual problems on it.
