Just one of the various NewsGroups I monitor regularly reports a number of
unread messages which, when I click on the NG to see what's there, is
reduced by the order of 10. This isn't a lot when the reported number of,
say, 20 is reduced to 2 but is a lot when the reported number of 300 is
reduced to just 30.

Does anyone know how this discrepancy arises and why it occurs on only one
NG please?

Thanks.
