Host Messages via a Wac file.
 

I do it on DFX with a with consol entries and text entried. The Consol is the top middle of the screen, and the Text is the lower left where the chat goes For example:

if Elapse(500) then //Text Message 1

text " "
text "A SandTiger Map"
text "Have Fun And Enjoy"


consol("DC's RULES: NO Bickering/Accusing, NO Bad Words or Names,")
consol("NO Cheat Codes, NO Name Calling, & NO NEGATIVE REMARKS.")
consol("I will monitor the game & punt or ban VIOLATORS. Just Have FUN")
endif

OBVIOUSLY, then you could type your weather commands below here. But the text commands between the " " are what pop up where the Chat messages do, while typed this way the concol messages such as a team message, or such as MY RULES, will simoltaniously pop up in the kill messages at the top center of your screen on DFX.
