How can I hide authors on thread index pages?

["Iain D. Brown" <iain@xxxxxxxxxxxxx>]

Dear fellow Mhonarc users,

I wish to customise the threads index pages so that only the
subjects are listed and link to the first message in the
thread, and that all authors of replies are hidden; viz,
instead of having:

  Arabic names
       Helen            [Instigator of the thread]
       Anthony          [Reply]
       Peter            [Reply]
  bibliographic software
       Linda
  CD-ROM Encyclopedia
       Ian
  Central London
       Jackie
  charging interest
       michele
       James
       Laura
       Margaret
       Laurence

I want a thread index page of:

  Arabic names
  bibliographic software
  CD-ROM Encyclopedia
  Central London
  charging interest

Is this possible? I have attempted to customise the example
subject.mrc file (with 50% success -- the subjects are
linked to the first message in the thread), but how can I stop
the authors' names appearing in my otherwise perfect thread
index?

Best wishes,

Iain.
