the forum is the best mechanism for that.
Just post something in the forum. That's it's purpose. To get that notification out to forum members.
I've searched and all the existing plugins are deprecated…
It will be cool if someone could create or update un existing plugin to gather the photos posted in a post or a category and then display them in a beautiful way (Masonry or Carousel) in a widget or a custom page
I believe it’s a missing plugin for NodeBB… I’ve tried to implement https://masonry.desandro.com with no success (I’m not a webdev )
was looking for the same thing. The question is how difficult it is to implement in an existing plugin for example featured posts etc.
