The sendout each week contains the following tables:
Most of this is fairly self-explanatory. PC's cash and dueling stats are hidden, but both given on a scale of 1 to 6 (cash class and dueling class, CC and DC).

Mistresses: B, I and W indicate Beautiful (+1SP), Influential (gains an extra bit of influence) and Wealthy (cannot pay extra to court, need not pay for her upkeep). Mme indicates someone's wife.
A complete list of all characters (including NPCs) is sent out separately (since it is very long).
The most important tables to look at are:
