Hi Marco
I'll ping you at the other site and link you to here. You can send me your email in chat.
It's a complex mod and not for everyone
Cool you wanna give it a try. If you do like it you probably won't be playing much OOB anymore 
I keep the rulebook in a window for easy access. I used to have two actually. One on the Table of Contents and the other one to scroll for the answer.

It's easiest for new players to be the Allies their first game as they are easier to play from a rule standpoint due to the large number of special German units.
We usually just toss everyone in the Deep End with all Options on. That's how we all learned lol but lately I think it's better not to use some of the newer ones such as Air Commander and Naval Commander.
We can use the A-Bomb if you want and or the Expanded Victory conditions. We probably should as I imagine most of us will going forward at this point. They just got added recently.
But it is a practice game, so on second thought, it be best not too. Don't wanna overwhelm you too much
Anyway Here's a link to all the rules not covered in the rulebook. Just scroll down a bit.

At any rate, we can sort out what and what not to use before we start.
