I think your users could check the new members of the TL0 group. The group is not visible to them on the groups page, but the link works https://meta.discourse.org/g/trust_level_0?asc=false&order=added_at. You could put that link in the sidebar (it doesn’t work for logged-out users, so using Discourse Group Sidebar Menus to show it only for logged-in users or a special group of trusted users might make sense).
Edit: Maybe it’s better to use the TL1 group because those users have already spent some time reading on the forum.
