PBEM or PBP Advice?

I’m looking to start a PBEM or Play-by-Post game with a group that has played one tabletop session - we just don’t have time to meet up often enough. Does anyone have any advice about this format? Does anyone have any advice on websites to try this on? I was thinking of tyrrying the Obsidian Portal site (http://www.obsidianportal.com/). Please let me know your thoughts and tell me about your experience playing MG using this format. Thanks.

I received a few responses to a similar question on this thread.
