There are several ways to get in touch with people. The most direct way is to use the contact form. It is great for those questions that need to be private or need a very direct answer.

There is also the forum. It is very handy for more general questions or just to converse with other fans of Nan Desu Kan. In fact, a lot of your questions may already be answered there.

Then there is the IRC channel on irc.freenode.net at #NDK. It isn't a support channel at all. Just a place for the hardcore to sit and chat. Any regular IRC client will due, but you can also use a web based client located at http://irc.ndkdenver.org.
