hare krsna,
originally the group AI for content creators can write to the AI-categories, while everyone can see the posts & comments. it appears that (some of) our new members have an interest in the subject and, not belonging to that group, could post only in the general category.
i’ve changed permission for the AI-categories now so that all confirmed users can post there (trust-level 1, which is the initial TL for new users). when it becomes clear who is interested in AI topics i’ll add those members to the AI group and we can tighten permissions again…if we find that necessary at the time.
