Campfire is an outstanding writing app that allows visual organization of project notes. Imagine being able to arrange the details of characters, magic systems, store photos, encyclopedias, research notes, etc.
The best part - I'll be able to share with you some of those notes (you could go on a tour of the world!).
Almost each module is $30 (one-time lifetime subscription).
I'm interested in 11 of the 17 modules they currently offer, and the total adds up quickly.
Putting fun in Fantasy. All my work is currently free to read online.
