Well, if someone wants to start a dutch forum, he can always contact the people of this forum and ask them if it is possible to add a dutch one. He should consider that he would be the first dutch moderator or he should at least find someone for that job.

Also there are other forums, in dutch in which you can ask questions about Linux in general, where I see also questions about Knoppix. The problem is, most of the answering people do not have Knoppix. A CD distro has some other problems than one on floppy or on harddisk.

The advance of adding a forum here is that most people can also search in english or in german. Most dutch people do know both those languages enough to read the answers.
