Might it be possible to embed twitter as media, similar to how one can embed a youtube video in a post?
Yup. Straight outta the googles. First hit too.. https://help.twitter.com/en/using-twitter/embed-twitter-feed
My apologies I thought you wanted HTML coding. for Xenforo you can either manually make a pict of the tweet and post or the Forum Admins can implement a custom BB code for it via addins..
At some point MacRumors will upgrade to the latest version of its forum software, which will include support for embedding tweets. No schedule has been established for the upgrade. In other words, the feature is coming, but not immediately.
