Here's what I've done that works real good:
At to top of the screen click on Tools, options,
display, tags, add, clean list, click on the box to
the right, and tag it black, ok, add, trash list,
click on the box to the right, and tag it pale
green, ok, ok.
While viewing rec.aquaria.marine.reefs, click on
Tools, Message Filters, Make sure it says, filters
for rec.aquaria.marine.reefs. Click new, create
filter name "clean list", match any of the
following, from, contains. Add a regular user, then
click "+", and do it again with the other regular
users. Then perform these actions, Tag message,
Clean list, ok. Click new, create filter name "trash
list", match all of the following, perform these
actions, tag message, trash list, ok, then close window.
And I also created a troll list.
