In gametypes such as Capture the Flag or Bombing Run, UT2004 announces when you attain or loose the lead. MapMixer extends this feature by optionally notifying clients in Deathmatch style gametypes of the following states:
For example, if you become the match leader then you will hear an 
announcement of "taken the Lead" and if you loose the leader position then you 
will hear "lost the lead".  If you become equal leader then you will hear 
an electronic chime and if you loose your equal leader placing then you will 
hear another electronic sound indicating that you have fallen behind.
 
This announcement feature is normally enabled for each Client but individual 
clients can locally disable this feature if they desire.  In the
Client Config Menu in the Options Tab there is 
an option called Leader Sound Notification that enables or disables this 
feature; it is on by default.
Each Client can also modify the default sounds used for the notification events.  
The Client should open their local MapMixer_Client.ini 
file and alter the following lines in the section 
[MapMixerClient-235.MapMixer_ReplicationInfo] (or add these lines if they 
don't appear - taking note to set the correct MapMixer version, which in this 
example is 235):
sTakenLeadVoice=Announcer.takenlead
sLostLeadVoice=Announcer.lostlead
sTakenEqualLeadVoice=GeneralAmbience.beep10
sLostEqualLeadVoice=Activates.mactiv70
Each line specifies a UT2004 UAX sound package and sound name. The examples 
above show the default sounds.
 
Obviously a game administrator will want to pick which game types that this 
feaure is used with. There is no point in using this feature with game types 
such as CTF, BR or AS as they already have their own similar notifications. 
MapMixer comes pre-configured to use its Leader Notification with Deathmatch, 
Team Deathmatch, Last Man Standing and Mutant.  However, if you create any 
of your own MapMixer Custom Game Types (eg Instagib Deathmatch) you will need to 
let MapMixer know that you want to use the Leader Notification feature with 
these game types!
To do this, go to the Game Types Tab in the 
MapMixer Options.  Down in the bottom left of the screen there is a button 
labelled In-Game. This button opens the Game Type Leader Notifications 
window, which displays a list of all the basic game types as well as MapMixer 
Custom Game Types. There are two columns displayed, the first displays which 
game types are enabled for Leader Sound Notification and the second column is 
used for the Player Ranking List HUD 
feature.
Simply double-click in the first column in the corresponding game type to enable 
or clear the Leader Sound Notification.
This not only works for offline single player mode but also for networked games. 
If you are setting up a game server, you can select which game types will be 
enabled for the audible notifications and then each client can switch it on or 
off for themselves via their Client Config Menu.
