I use Thunderbird to read newsgroups. I added a filter to delete the

This morning there were 111 headers in r.b.c. When I selected the group,
the number dropped down to 18 - all real content!!!

Add NFILTER to that to kill all crossposts. Then it starts to look
like it used to.

Thunderbird should have this capability, but for some reason they have
it disabled.
