The Bookmark function has been running for 6 months. I was never happy with its implementation, but I couldn’t find anything better.
However, I now find that is interfering with other parts of the site, slowing things down, and leaving remnants of itself in the oddest of places.
So I will be switching the function off at the end of July 2018.
All is not lost: every web browser has a similar function, called either Bookmarks or Favourites. Simply create Bookmark/Favourite folders in your browser, then when you have found a page on my site that you know you will want to keep returning to, just use your browser’s bookmark function.
I will leave the function on this site running till the end of July in order to give you time to duplicate any bookmarks you have made on my system, but after that date all bookmarks on my site will be deleted.
