If you did it by stringing together replied posts, that could work but would create spam on a lot of tls. In the comments sections of a post, maybe, generating a fresh post upon major scene changes? Either way it’s a stress test of the ui and I’m interested in seeing how it’d look in practice
I mean, if we're working with the interface, then each player would create a page for their character, right?
This would definitely ameliorate the issue of spam on tls, but I'm still not sure how it would look and feel in practice.
