I'm translating a PBP to a Story Hour right now. I'll link it at the end of the post. It seems like it would be rundundant, but it's really not. The PBP I'm in moves really fast, with some players posting more often than others. Those who aren't around as much will often make responses to things pretty far back in the thread.
Also, at least in our game, the PBP style format allows us to split the party far more often. So you might have posts for two or three scenes going on at once. When I do the story hour, I get the posts that go with each scene all together, put the comments in an order that makes more sense, etc. It becomes a much smoother read.
I think it's a lot less work than a regular story hour. You don't have to remember or write up from tapes. It's mostly written for you, you just have to copy and paste, check spelling and such, and post away.
So here are the links.
Here There Be Vampires... The Story Hour I am writing up. It's the third adventure mod for this group by a guest dm. My style of putting it together is different than our usual Story Hour chronicler.
Revenge, Renewal, and the Promise of a New Year The first adventure, written up by SilverMoon, our usual GM. Start here if you want to know the characters better. It's almost complete now.
Wizards, Whiskey, and Wonderful Things The second adventure. Not even halfway through the adventure yet....
Warning: Starting anywhere other than the beginning will be spoilerific if you decide to go back and read from the beginning!
