It would almost certainly be a community with very few if not zero active posters, and there's already a few relevant communities on .world, and nothing's stopping people from posting d/Deaf or HoH-related content on other communities... But even keeping all that in mind, I still think having a /c/deaf would be nice anyways.
The community could also be called /c/dhoh or something else entirely, it depends on what people prefer.
How does this process work, anyways? I take it that this request has enough upbears to be seriously considered for creation, so is it now like during the next mod drive there's going to be a section for people who want to moderate /c/deaf, and then after that the community will be created?
Once someone volunteers to moderate it I'll send a mod application and when it's filled out I'll create the community
