Hello, 

I am considering Wednesday 27th (next week) at 14:00 UTC to do this change.

If no one says otherwise, I will go ahead and schedule it.

Thanks

Manuel.

Sounds good. I think it's probably just easier for us to restart mailman
and mailman-web soon after to find any issues right away than later on.

Sounds good! I will email this thread and update the task once I've decided a day/time for this change for next week.
