I was interested with DTM API and found a page on the subject on the ZUG site. Some links are broken, I decided to contact the original author and he told me he no longer program for the Z, but he managed to send me all the required docs and samples. I tried to edit the page in order to remove outdated stuff and replace broken links without success. I suppose only the original author can edit the page, is it possible to transfer the ownership of this page to myself or have someone else update it? I just don't want to be selfish and keep all the info for myself...
