Re: Running Mixminion for Testing

[Tom Ritter <tom@xxxxxxxxx>]

Hi Florian,

Unfortunately I don't know the answer to this question.  You could try
to email Nick and see if he is able to help.  For what it's worth, I
think that mixminion doesn't/didn't support auto-publishing to the
directory, and that new nodes needed to be added manually.
