I’m not quite sure what the formatting for a link needs to be in order for Discourse to style it appropriately. I think half the time I post a link, it ends up being posted directly as a link like in this thread.
Is there a certain format I need to post links in for them to be formatted attractively?
This is a link to a private post in a public post – it cannot be oneboxed because it would leak the content of the private post.
Which post was private? The link goes to a post within a category that is visible to users of all trust levels. Only staff can create in that category but it is not private.
The link https://community.c9.io/t/what-are-active-workspaces/1334/2?u=bradydowling you posted requires me to log in:
I can read the source post (https://community.c9.io/t/sharing-premium-workspaces-with-free-users/2741/2?u=bradydowling) without logging in, so showing the preview would leak the What-are-Workspaces-topic to me.
Perfect! Needed to change the settings for that category. Thanks so much for explaining that clearly
