Ozlabs patchwork notification not working anymore

Hi Stephen,

If I remember correctly you maintain the Ozlabs patchwork aren't you ?

For more than one year now, patchwork for linuxppc-dev hasn't sent 
notifications about patches status changes. Last notification I received 
was 11 June 2024.

Is there a reason for that change ? I recently got questions from people 
asking me why they didn't get notified when I started looking at their 
patches.

Is it possible to restore previous behaviour ?

Thanks
Christophe
