Instead of having messages for 2-9 players moving as a party, would it be
feasible to implement something so that something different be show, to reduce
spam?

For example, maybe like

<PartyName> arrives from north.
<PartyName> leaves south.

Just a random idea.

Since there is no 'who <partyname>', better would be if it showed "A party led
by <playername> arrives from north", maybe including the number of people in
the party.

If party movement would be handled as a whole and not like now when each party
member is moved realy fast after each other, it would also solve the
(relatively rare) problem where monster gets killed when only part of the
party has moved to the room while the other half is still in the previous
room.
This has the nice effect of outsiders geting cut down share of the exp from the
kill but also it screws those that need to be in the room when the monster dies
to get reputation/tasks/other nice things.
It would propably be a pain in the ass thing to code (or not), but much valued
as when i happens it realy sucks.

A hits you.
