You can now embed Tweets much more nicely in your forum posts. Simply paste the link to a Tweet on its own line and it will be formatted like this:
https://twitter.com/f1fanatic_co_uk/status/230245170271105024
The change is retroactive so you can see it on some threads already such as this one:

You can already embed videos and images from sources such as YouTube and Flickr in the forum, see here for more information:
