[Mailman-Users] can't find mailman Archives

[liulin2009 at ict.ac.cn]

Hi,I use mailman to create a maillist named mailman,
when I hit the Mailman Archives , it turn to a Mailman Archives page,
but i can't find my archives, the page show:"No messages have been posted
to this list yet, so the archives are currently empty. You can get more
information about this list. "
in fact, i find the archive file in directory "/var/lib/mailman/archives/..."

i don't know what's the problem.
look forward to your answer.
thank you!
