I want to be the first to run a 4th edition play by post. And you know what? I'm going to run it all based on speculation. Who's with me?
Just don't play an elf, they're outlawed.
Tieflings are okay. And so are Djinni.
Clerics are not. 4e is secular, after all.
Just grab Dawnforge by FFG from the ENWorld/RPGNow store and, using the rules for racial advancement, play 3.5E but pretend it's 4E. You'll be part of the way there....
