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)
