ok well i guess its a matter of adding a warning to the bottom of the warnings config file . Something like this
[Warning33]
ID=HeavyFog
Category=Info
DurationOnScreen=infinite
DurationUntilCanBeDisplayedAgain=0
CommandsWhenClicked=
BlinkWhenActivated=No
add the appropriate warning in the menu editor , then add an icon onto the hud dds .
Who wants to do this

its beyond me .
