How to create private whiteboard-server?

[amazalot]

i already got the server installed but no modules and anything else.
Preferably id like my server to support this:
http://www.unionplatform.com/?page_id=3815

But the chat and username is not essential.
Thanks a lot!

You could just download the source code from the page and just remove the elements you want.
