It is late so this is quick and to the point.
The webiste Pathfinder Chronicler is "a group of professional and non-professional writers creating works based on Paizo’s Pathfinder® world of Golarion. Our goal is to create “publishable works” that we can proudly present on our website."
Check them out here.
Also I found a thread over on the Dragonlance Nexus forums about a site called macrayskeep that facilitates playing on line. I haven't checked out the site yet, but I'm pretty sure it is play by post. Check out the Dragonlance Nexus forums for a list of the available games, which range from 2nd edtion D&D to Palladiums System games, as well as another link to the site.
