Version 2.02 questions

[Cam]

Hello all
Been awhile since I posted here ! Haven't played in awhile as well ! Okay I downloaded version 2.02 in a fresh install. Must say, it is quite nice. Takes a bit of getting used to but am quite pleased !
So, opponents also have to have 2.02 installed as well to play pbem ?
What does the generic mod enabler do ?
What about all the extra Balkan, finnish stuff etc. I don't see to many new scenarios in the menu ?
I had also enjoyed playing a few of the Korean War scenarios in the past, I am assuming it is a separate install again ?
I realize some of these questions may be redundant
Thanks for any feedback
