The SP (Send Personal) command  is used to send a personal message,
i.e. one which is targeted at a single individual.
   Syntax: SP <to> [ @ <at> ]
The <to> field must contain the recipient's callsign. The <at> field
is semi-optional, and consists of the callsign of the recipient's
"home BBS", plus other routing information where necessary. 
This mailbox contains a database of known active mail users, called
the "White Pages", or WP for short. If the recipient's callsign is
known to WP there is no need to enter the <at> field, as the mailbox
will automatically supply it.
If you enter an incomplete address, the WP attempts to extend it, but
if you enter a full address, WP assumes you know best, and does not
intervene. Therefore if you do supply a complete address, make sure
it is EXACTLY right, or your mail may get lost.
   Examples: SP G8PZT   <-- No address supplied. WP will supply it
                             if recipient is known.
             SP G8PZT @ GB7PZT  <-- Partial address supplied. WP will
                                     attempt to extend it.
             SP G8PZT @ GB7PZT.#24.GBR.EU   <-- Full address supplied.
                                                WP won't intervene.
If you're sending a message to another user of this mailbox, you
needn't enter the <at> field.
If you're sending a message to a user of another mailbox, you only
need to supply an address if the WP doesn't know the recipient.
If in doubt, use the "I <callsign>" command to check if the recipient
is in the WP database.

The SR (Send Reply) command is used to reply to a message that you
have just read.
   Syntax: SR [msgnum]
If you don't specify [msgnum] it is best to use this immediately after
reading a message, because some commands cause the mailbox to "forget"
the last message you read.
The mailbox automatically fills in the address, and prepends "RE:" to
the original subject. The reply will always be a private message, even
if you're replying to a bulletin.
You will then be prompted to enter the message text in the usual way.
It is advisable to use the "SR" command in preference to "SP" wherever
possible, to reduce addressing errors.
   Examples: SR     - Send reply to message you just read
             SR 123 - Send a reply to message number 123
See also: SB, SEND, SP

The U (Unread) command "un-reads" a message (marks it unread).
   Syntax: U[nread] <msg>
Users may only "unread" their own mail.
   Example: UN 357 - Unread message 357

The WP (White Pages) database on this mailbox is part of a world wide
distributed database, which holds details of all recently active
Packet users, and is primarily used by mailboxes to make mail routing
decisions. The data is also available to users via a number of search
commands.
The data is collected from two main sources:
   1) from the details a user enters when they register on a mailbox.
   2) from the headers of mail in transit.
Most mailboxes with WP capability share their data by means of
regular "WP Update" messages.  These were supposed to be sent to
"regional" servers, which would collate the data and send it via
regional and national servers to a world server. This system has all
fallen apart over time.
It is important that you nominate only ONE BBS as your "home BBS", and
only send messages from that BBS, otherwise WP will assume you've
moved BBS and will get confused.  Your mail WILL DEFINITELY be lost!
If a user has not sent a message, and has not re-registered on a BBS
within a certain period, his details are purged from the WP database. 
The period is commonly 90 days, but can be as low as 30 days. 
There are many packet users who NEVER log into a mailbox, and who are
therefore "invisible" to WP.
The local database can be searched using the I, I@, IC, IH, IN, IQ
and IZ commands,for which help is available.
