The MusiCAD forums (yes there were two, one in Dutch and one in English) were the place to ask questions and get answers.
Due to forum spam and all kinds of hacking attempts via the (outdated) forum software, the forum is no longer in use.
Questions that you ask by email (and were not yet answered on the wiki) will be answered there.
Generic questions received by e-mail might be copied to the MusiCAD wiki and will be answered there.
