My PBEM Registry.
 

Although I've been playing Civ for a while, I'm pretty new to PBEM. I've recently started playing in two Conquest-based PBEM's at Civfanatics, one based on Rise of Rome, and one on Age of Discovery. Akots recently invited me to play a 1v1, [duelist] so we'll be starting that shortly! Anyway, this thread will just contain links to games I'm currently involved in.
