RE: FT PBEM (was: Anti-missile defenses

I wondered if anyone has played a PBEM game of FT in a day or less.  I	

realise that not everyone has access to the web instantly available, but
  
I am sad enough to want to try a large battle with many players at some 
 
point in the not too distant future.

Newbie SG2 question:

What are the rules for unit coherancy for squads in a platoon - do they 
 
have to be within 2" of another squad or what ?

PBEM: SG2 or Dirtside
Has anyone tried these as PBEM ?
