Hi, nasshi. Welcome to the SMAC section of ACS!
I am a CMN and I can setup a PBEM for you.
Recently there was another new SMACer Solardust looking for a PBEM here, but his last activity on the site goes back to June 27. Try to contact him, maybe he will respond. Also, I think drow21 may be interested in a new game.
I can try also to advertise on another site to see if someone is interested in a PBEM with a role-playing component.
