 In general, each server receives, stores, and transmits *one* copy of a 
 crossposted message.  On each server, that single copy is somehow "linked" 
 to each of the crossposted groups that that server carries.  On UNIX-based 
 servers, for example, each newsgroup may be represented as a file-system 
 directory (e.g. /usr/local/news/spool/articles/news/groups/questions/), 
 with crossposted messages "hardlinked" to the appropriate directories. 
 There are other ways of doing this, but this is the simplest and 
 traditional way.
