Most communities are not the sole community related to their topic, there are really often other communities on the same, or similar topics.
An example: there are a tonne of art related comunities, but only a small handful of them have links to other related communities.
It would be great if there was more of a culture of propping up semi-related communities. This would be particularly useful for helping more niche communities get rolling.
I agree! If you DM the mods or make a meta post, I feel like they’d happily add a section. Sometimes they aren’t aware of the other communities
