I recently came across a nice piece of software for DM’s of 4th Ed. who need a little bit of help organizing and keeping their campaign stuff in order. The program includes flowcharts for your adventures that link to encounters, maps, and all sorts of stuff. You can even use Dungeon Tiles to plan and map out your encounters!
I’m not doing it any justice by writing about it here. Just go check it out yourselves.
It’s called Masterplan, and I found it on the WOTC forums. The designer posts by the name of Devereaux on the boards.
Go check it out!
