Setting the guidelines seem the hardest part to me (besides having the time to do it); I know I would be hard put to draw the line between "sure, go ahead" and "would you like a free casting of the Wish spell every turn on top of that?".

I am quite fond of PBEM myself, both as a player and as a host. Having your turns delivered in your mail is so convenient for the lazy player (myself included), and PBEM allows for a more flexible schedule, while being much easier to set up. If only my mail server bounced when it fails to deliver a message to my address.
