rn again - seeing articles more than once

[interran at Shasta.ARPA]

Anyone else who see articles cross-posted to more than one group more than
once, i.e., in every group the article's posted to?  I got the impression
from reading net.announce.newusers that cross-posted articles were supposed
to be seen only once, but that doesn't happen with rn.  Am I wrong or IS
there a way to avoid seeing 'em more than once? 

Again, a reply by mail would be best. Thanks.
