[ardour-users] joining ardour-dev ?

[Dave Phillips]

Greetings:

  When I try to sign up for the ardour-dev list via the page at 
ardour.org I keep getting this error after replying to the confirmation 
mail:

   ----- The following addresses had permanent fatal errors -----
<ardour-dev-ardour.org-request at ardour.org>
    (reason: 550 <ardour-dev-ardour.org-request at ardour.org>: User unknown)


Can anyone here tell me how to sign up for the dev list ?

Best,

dp
