[LM_NET] Question about Listserv Prefixes/Protocols

["Ronda Y. Foust" <rfoust150@COMCAST.NET>]

As a newbie to the site (and to listservs in general), I was  
wondering if there were a place that listed some of the prefixes that  
are used in the subject line.  I notice that some of the ones used are:

Target
TAR
Hit
Gen
Mid
Tech
MS
Sec
Share

I'm pretty sure that I understand that Gen = general, Tech =  
technical, MS = middle school, Sec = secondary, but I'm not sure  
about how to use Target (TAR?) and Hit.  Is there a protocol (formal  
or informal) and are there some other handy prefixes to help when  
browsing the posts?  Also, are these prefixes used in other listservs?

Many thanks.  I've been enjoying the discussions and insights  
everyone has been sharing.
