@niro That's right... I encourage plugin writers to use the scripts property in plugin.json over the scripts.get hook if at all possible, as the script is then minified on production.
@Hope33 when you activate shoutbox and rebuild restart it should add a new route at yourforum.com/shoutbox you can also drag and drop it as a widget on a page.
Yeah I stopped maintaining that a while ago, it was a good exercise and an example of how to build a plugin but ultimately it’s redundant: markdown already has the capability to insert images.
