Interesting, this is a feature that @Falco added a while ago: FEATURE: Web Share Target Support · discourse/discourse@efec2db · GitHub
It’s supposed to pass a title and text parameter to Discourse, and then Discourse triggers a composer window with those params prefilled.
Do you know if sharing on apps other than Linkedin pass these parameters correctly? I.e. does “share to fcDwa” work well when sharing from somewhere else, say text selected in a browser?
