Since my "King of Absalom" idea hasn't gone very far (see previous blog post), I have another idea: tag teaming.
I've found that having someone else working on the same topic really helps motivate me. Topics can sometimes be confusing, or there can be contradictions in the timeline, and having someone else to bounce ideas and problems off of really can help. Edits are also made easier, as you know that the other person knows a particular topic just as well.
So would anyone like to tag team? I'd let you pick the topic. I'm happy to work on anything, as I have pretty much everything Paizo has published. Favorite topics of mine include: the Darklands, the Great Beyond, and monsters.
