Thanks for the link.  Since APRSISCE/32 doesn't "archive" then I'm 
thinking it doesn't apply to me.  Or is it supposed to be "don't archive 
or display"?

An interesting conundrum is whether or not the archival sites are 
expected to remember the !x! from a beacon and suppress recording 
messages as well, or if it must appear in each and every packet?  And if 
you're expected to remember it, doesn't that mean that you're archiving 
some information about station that has requested to not be archived?  
Gotta love/hate ambiguities.
