I know that a lot of people have signed up to this jam who have never written adventures before. In the next couple of days I'm going to put together a list of resources that might be useful for you, but in the meantime I've started working on my entry and I decided to blog my way through it so you can see how I personally go about putting an adventure together.
Obviously this isn't a definitive How To Write An Adventure guide because everybody works differently, but I thought it might be useful to see at least one way of approaching thngs.
The first post is here.
