For those of you who haven’t followed developments in the comments, there is a significant change here at SU. John Wight will be publishing his writings elsewhere, and we wish him luck, and every success for the future.
John has relinquished his editing and admin rights at SU, and if you were banned by John, then welcome back. I have asked Tony, who brilliantly assists with technical support behind the scenes, to “unban” people (it is quite beyond me). This may take a while to percolate through, so please be patient.
