PBEM : Mirror Matches with CMAK

[candyflip]

Hi all,

New here from the land of Oz.

Westland has challenged me to a battle in PBEM, which will be my first ever game (ANY game) against an email opponent. Sheesh - talk about trial by fire!!

However, having read the CMAK manual thoroughly, and any online resources I could find (including here and Battlefront.com), I'm unable to find anything about a 'mirror match', which is what I'm apparently engaged in with Westland.

Is there a link I can find out more about these battles (how to work them?). I'm sending only 1 fil back to him (my changes) but I'm supposed to do something with the other file as well (I'm Allies, he's Axis, but I'm supposed to do something with his file as well??)

Sorry I'm an absolute newb on this and a native English speaker might make it less painful for me, and him.

thanks

jon
