Help
From OpenKM Documentation
This menu, as well as providing help on the functioning of OpenKM, allows you to send comments and error notifications (bugs) to the system developers.
There is, furthermore, the option of requesting support via the web on the system operation, or to access the OpenKM discussion forums. Other options include access to the project website (http://www.openkm.com) and the display of product credits.
In the version notes you can find the changes that have been made compared to the previous version.
