There are many ways to get help with running your Kolab software.
Read through our mailing lists and send us a message. Our members there would be happy to help. Alternatively, speak to the community directly on our IRC channels, which include #kolab and #kontact. If you have not used IRC before, you might want to have a look at a tutorial.
Kolab Systems, an independent developer and supplier of the Kolab groupware, can provide you with the best possible support for your installation.
