HPS Waterloo vs. Matrix Games Tiller's Battleground Napoleonic Wars

[FroBodine]

Hello,

I own HPS Waterloo. My opponent owns the Matrix Games Tiller's BattleGround Napoleonic Wars, that includes the Waterloo battles.

We want to play Quatre Bras. Will our two versions talk to each other in a PBEM game?

If so, is there anything special we need to do?

Thanks!
