That's something I've been thinking about this morning. I do post updates to Reddit sporadically, but honestly I really hate Reddit's format and I don't think it really fills the same niche as a forum thread either way.
I've been thinking it might make sense to make a development blog or something where I can post smaller more regular updates, and then dump new editions or expansions to Reddit?
I've also toyed with the idea of making a Discord server for this hack, but I'm wary of that because moderating a Discord community seems like it could turn into a headache incredibly quickly.
Open to suggestions!
