The discussion revolves around the inability to invite users to topics in categories that are not visible to anonymous users, even if those users have Trust Level 0 permissions to create, reply, and view. mentalstring notes that the invite option is suppressed in such cases, which seems to prevent invites to topics users might not be able to access. JimPas clarifies that only Trust Level 2 or above can send invites, but mentalstring confirms this occurs even for TL3 users with default invite settings. simon explains that this behavior is due to Discourse’s attempt to prevent invites to restricted topics, though it’s problematic since TL0 users can access these categories. codinghorror suggests it might be a simple bug fix. patpeezus asks if the issue was resolved, and JammyDodger confirms the behavior persists, recommending it be treated as a feature request.
In some topics it’s not possible to invite another user to the conversation. This happens when it’s in a category that is not open to everyone, which might make some sense in the case of something like a Regulars Lounge category. However, if a category is just not visible to anonymous users (but even a TL0 can Create / Reply / See in it), that already prevents inviting other users to the topic.
I think the logic being applied is to prevent someone from sharing a link / invite by email (which makes sense) but is also preventing inviting existing users by their username.
Does this happen for all users?
Users with a TL0 or TL1 cannot invite others and won’t be shown the invite link. Only TL2 or above can send invites and get shown the invite button.
I can reproduce this on my local development site. Even as an admin user, when I set a category’s security permissions to Trust Level 0 can Create / Reply / See, the share dialog doesn’t give me an option to send an invite. I think that Discourse is trying to prevent invites being sent to topics that a user may not have permissions to access, but all users on the site will have TL0 status, so preventing invites from being sent doesn’t make sense for this case.
Just giving it a quick run-through and it still seems to be the same behaviour where the invites will only be possible for normal users from open categories (ie. a Trust_Level_0 catgeory will suppress the invite option).
