It currently appears to be capped at 65'535 characters. Could it be extended to at least preferably 250'000 or so characters? I have made single-character posts breaching 50'000-character mark, and some of my nation sheets have effectively made it past 80'000 characters. The world information compendium of a RP I am in contains over half a million characters total, and I have seen plenty of others which go over 100'000 characters.

(While we are at it, could you consider including a tab for storing world information / summaries aside of OoC/IC (and CSs, if it gets added)? OoC is too big to effectively search for info, and if we were to add the world info into opening posts, then currently it would require a dozen "reserved" posts in the OoC's beginning for extensive-world RPs.)

I'm currently hard-limited to 65535 characters by my architecture. At least for now.

Going beyond it is something I'd like to do, but it will take more work for me than bumping up a 'max-post-size' limit.

Yeah, I'm working on letting GMs add arbitrary tabs.

Could you elaborate on which part of the architecture is the limiting factor? I could perhaps figure out a workaround (until then, I hope the site doesn't have any issues with intentional multiple-posting - I had to divide a character sheet between *three* posts just to make it fit in the last RP I joined).

I can't comment on the architecture side but as to the intentional multiple-posting, given its context it's completely acceptable.
