we don't have your death system bro xD you didnt tell us version of ur engine either.
My guess is that you have something like that: (guess based on assuming that you have tfs 1.x)
Lua:
player:sendTextMessage(MESSAGE_STATUS_CONSOLE_BLUE, "death notification sent on chat.")
and you want it to change to: (or paste below it)
Lua:
player:sendTextMessage(MESSAGE_EVENT_ADVANCE, "death notification in the middle of the screen")
If you dont paste your code/tell engine version then you wont get more help than this.
Also, in future don't select this forum board, you should go to support.
