Hi,

I now how to add my own menu, via lua to the F10 - Other menu.
To make this available all the time I Added it to ...\DCS World\Scripts\MissionScripting.lua
 

I added something like this:

missionCommands.addCommand( "menuName", nil , callBack, nil)

How, and where should I add this so that this menu will be available in MP as well, or is this not possible?
