[Mailman-Users] -1 request(s) waiting?

[David Purdue]

I am using mailman 2.1.5 on OpenBSD 3.6 sparc64.

I am in process of migrating mailing lists to this machine from another, 
so the lists are all set up but are not currently handling mail.

But I am getting a daily reminder from mailman on this machine (mailing 
list name changed):

=-=-=-=-=
Subject: -1 [List] moderator request(s) waiting
From: [list]-bounces@[domain]
To: [list]-owner@[domain]
Date: Sat, 08 Jan 2005 08:00:03 +1100
X-BeenThere: [list]@[domain]
X-Mailman-Version: 2.1.5
List-Id: "[List description.]" <[list].[domain]>
X-List-Administrivia: yes
Errors-To: [list]-bounces@[domain]

The [List]@[domain] mailing list has -1 request(s) waiting
for your consideration at:

         http://www.[domain]/mailman/admindb/[list]

Please attend to this at your earliest convenience.  This notice of
pending requests, if any, will be sent out daily.
=-=-=-=-=

Why would there be -1 requests waiting, and where can I go to correct this?

Many thanks,
