If I’m understanding the request right, it’s to display on a taxon page the type of reproduction/sexes for a species vs. to decide here how individual observations should be annotated. Let me know if I’m misunderstanding.
The latter can be done on the Let’s Talk Annotations topic. Future discussions about specific sex annotations or how reproduction works will be moved either to that topic (or Nature Talk if more relevant).
e.g. for Helix
If the request is to allow any user, or any curator, to edit how sex annotations apply to taxa, I don’t think the request is viable. Only iNat staff edit annotations, not users – that’s what observation fields are for. Given the extensive discussion about sex and reproduction above and in the Let’s Talk Annotations topic, I think we can all see why this would be a part of the site that is more locked down/standardized than left to the community to curate.
