I made a commitment to publish on a certain date which seemed achievable, but I failed to make it. I’ve apologised and I gave my reasons. I won’t be making any more commitments to do something on a certain date. I don’t think I’ve broken any promises other than one I just mentioned. This project has cost a lot of money and in no way has it financed holidays to Spain etc, and I utterly refute all the unpleasant comments and suggestions posted here lately.
