Indeed. Actually the problem was that Calc.org file upload policies were really weird during their final years before the supposed redesign. After uploading your own game, you had to get a friend or another member to confirm that it's your game via e-mail. At the time I barely knew anyone from the community who could do that, so I never did. However, after the second redesign started, where only a file archive and the forums were available, somehow they decided to process those files the same way ticalc.org does.
