Highlights system is opaque

What on earth are Highlights? I’ve got a couple which I imagine is a good thing, but no idea what they are, or what got highlighted.

I believe it’s when someone is on your profile page and clicks “highlight posts.” All your posts will appear highlighted green to that person.
EDIT: yes that seems to be it. In other news you can highlight yourself :stuck_out_tongue:

I also think that if you give a person a certain number of medals then their posts will be automatically highlited for you. I think.

The downside would therefore be the number of people Ignoring you… :slight_smile:

People who you’ve highlighted - given enough medals to - have their posts shown in green. Also toggleable per profile.
Usefulness: when a thread is all green I know it’s quality ;D
