https://greentalk.org.uk is an alias for greentalk.uk and can safely be used instead.
Existing bookmarks to http://wp.greentalk.org.uk/page-name/ will probably work if you switch to https and remove the initial wp. and also remove the trailing slash.
Or simply go to https://greentalk.uk and find the link to the post you want in the date and title list in the right-hand column.
