Apologies In Advance - How to Unsubscribe?

  Apologies in advance for sending this to the entire list, but I've
tried the other usual routes to no avail
(rubygems-developers-request-GrnCvJ7WPxnNLxjTenLetw@xxxxxxxxxxxxxxxx, -owner, 
mailman commands,
etc.)

  I'd like to unsubscribe to rubygems-developers.  Mailman seems
unwilling to do so, although I've tried a couple of times and have
responded to the eventual auto-reply.

  Can someone help?

  Thanks,

  -bws
