A series of possibly linked facts has become evident. They may, or may not, be of interest to readers.
The Society of St Catherine of Siena has disappeared from the internet. Its web address was http://www.caterinati.org.uk/ (Here are some remains.)
The Journal Usus Antiquior is now edited by Ben Whitworth. (Recall the launch.) It is no longer linked to the Society of St Catherine of Siena (though see the Facebook page).
Dr Laurence Hemming no longer describes himself as a Deacon of the Catholic Church on his website.
I don't know what to make of all this; the full facts are not available to me. I don't think it is terribly important. It is a side issue.
