I'm looking for a small group to play the Iron Gods AP. If you're in the Treasure Valley, great. Otherwise I play PbP on a small site for gaming where I have more control. I have years of experience running games live and PbP.
I'm pretty sure it's okay. Paizo is very open-minded. The PFS PbP Venture-Captain was on the Know Direction podcast this week and mentioned Myth-Weavers several times as a good site for play by post.
