I'm not sure if this is the right board to post this kind of thing. If it's not, mods please put it in the appropriate board. Thanks!
Some of my favorite sourcebooks are the NPC and Monster codices, which provides statblocks for encounters and sometimes a simple writeup of the character in question. But these books don't contain a lot of the newer classes, and there's a very distinct lack of non core base, hybrid and occult NPC statblocks ready for use. I also find it hard to find characters of rare and unusual races.
Two days ago I posted a similar thread on Reddit's r/Pathfinder_RPG, and got a lot of approval and support. The idea is that everyone contribute a few characters, either unique NPCs they built for their own home games, or PCs they are currently playing or have played. It's minimal effort on each person's part to share these existing characters, but once compiled it would be very interesting for DMs to reference and use as plug-and-play encounters. And if character builds and backstories are interesting, it could make a nice read on its own too!
The codex, once compiled, would be a large PDF containing a whole lot of uniquely built characters from level 1 to 20, arranged alphabetically by class and by CR. The format would be very similar to the NPC Codex and the Inner Sea NPC codex. As the editor of this project, I will be giving priority to non-core classes and uniquely flavorful archetypes of core classes.
