I agree, keep the missions in the mission section of the clipboard. I already get sick of people jibberjabbering on and on about whether or not the mission will get spy'd out before we even launch.
I would also suggest refraining from asking the mission leader specific questions about the mission on country channel, everything you truly need to know about the mission is shown on the clipboard. If a person needs to take their own plane, I suggest joining the mission then doing a .goto mission planer or .move mission base to ask specifics in the tower.
A side note here. You can actually take any plane you want in a mision.
Just get your desired plane ready in the hanger and join the mission. When the mission asks you how you want to score your sortie, spawn your plane before clicking Attack / Fighter.
