This is the home of our official IRC channels, they are:
#duion.de (for german speaking people)
So you can go there, if you have questions or suggestions or just want to chat.
How to reach?
If you don't know how to use IRC yet, let me give you some recommendations:
1. Use the freenode webchat: http://webchat.freenode.net/ simply chose a nickname, enter the channel you want to join, type in the captcha and done.
2. Use a regular IRC client and connect to the channel there, here is a comparison of all available clients: http://en.wikipedia.org/wiki/Comparison_of_Internet_Relay_Chat_clients
I recommend the client Pidgin: https://pidgin.im/download/ It is a multi messenger that is compatible with most chat protocols as well as IRC.
