The S command is used to send messages. It several formats:
SP call @ bbscall.haddr  Send a private msg  Ex: SP K8EIW @ WB8BII.OH.USA.NA
ST zipcode @ NTSst       Send traffic msg    Ex: ST 44070 @ NTSOH
SB category @ route      Send a bulletin     Ex: SB NEED @ ALLOH
SR msg#                  Send reply          Ex: SR 12723 or SR 12723.

In SB if call is a user of this system you can omit the @ bbscall.haddr
In ST, NTSst means to replace st with the state its going to: OH for Ohio, etc.
In SR, if you put a period after the msg #, a title will automatically be made
by preceeding the original title with RE:
IMPORTANT: SR tries its best to determine where the reply should go, but
it is not always perfect! The same applies to the REP command.
Never uses SSID's in callsigns (ex: don't use WA8BXN-2, just use WA8BXN)

Hierarchical addresses are of the form state.country.continent. Other parts
may be used by a particular BBS, if you know them, use them.

When sending personal messages to a distant bbs, it is a good idea to put
the destination city and state in the title. 

When you are done typing your message, end it with either ^Z (Control-Z) or
/EX at the beginning of a line.
