Hello,
Every member from the old pywikipediabot-users mailing list has been added to this new, fast, shiny, no-spam-in-footer, etc mailing list. Once no bug tracker reports need to be sent to the old mailing list, that list will be closed.
If you find any bugs with this mailing list, please first check your membership bits (I have set them, but it seems I am human and hence error-prone) and if that does not solve the problem, please mail me or, if it is a mailman bug, put in on wikimedia's bugzilla.
