Links to the Birmingham mailing list archive

There is an annoying issue with such links. As soon as a new year has begun, the link must be changed to find it. E.g. the link to a thread from 2018 which then was

https://www.listarc.bham.ac.uk/lists/sc-users/msg62866.html

has now to be written

https://www.listarc.bham.ac.uk/lists/sc-users-2018/msg62866.html

Maybe it makes sense to always write both versions when refering to a thread from there …
