Thanks. I saw some people using the Brazilian community. believe people from Asian countries tend to use them, at least I saw Japanese communities filled with messages. I'm not sure if is something that is going to stick with the public, but who knows. Maybe you could make something similar to Steam forums on DEG Mods, a single forum for every game that has a mod, that could be nice.

I do want to post on these communities, so that when people come they'd find stuff and interact / post / reply, but there isn't a good client for them yet imo.
In regards to DEG Mods, I'm not sure if each mod would need its own community/forum, I'd imagine that's too much (current comment section should be enough, especially since there'll also be blog posts from the creator visible along those mod posts, which I think can also be categorized as well and presented in a way where those blog posts can be under a specific mod, creator can create a category list and it would be hooked up to their profile page, where even fans can post under that category. Will look into it in the future / see if it can be done).
However, if a Steam/Itch alt on nostr were to ever be created, then ya each game would have its own community page created by the game creator/seller (would be so cool if I'll ever come to create said project =3)
