Edit: there is a bug with this change but it’s only visual. If you submit a comment, it will say “Couldn’t find comment”. Refresh the page and your comment will show up.
The new Lemmy update introduces a feature that was starting to get requested a lot, which is that community moderators can make their community either visible or local only.
In the local only setting, only instance users (so lemmygraders in this case) can interact with the community, which I assume to mean creating posts, commenting, and up/downvoting.
We’ve thus made this community local only as per the description, it is for Lemmygrad users and admins to discuss administrative issues in a more transparent manner. This means people whose account is not on Lemmygrad will not be able to comment here anymore.
I think it’s also cool that votes don’t count on this community, that way people are forced to debate their ideas if they want to participate here.
But yes it’s a bug lol.
Also I’m not getting notifications in my inbox when someone comments on this post.
