The list is empty, that means the mod(s) of that sub didn't create flairs.
Mods would also have to enable "Allow users to flair their own posts".
I'll have to pay more attention to which subs offer flairs. The subs I've encountered with a flairs drop down list don't have the flair text I'd want and have seen used in the past.
Users can't create flairs, they can only select them (if the sub permits it) from a list created by mods.
You can ask an active mod in the sub you'd like to have a specific flair to add it in the list.
I've noticed a few folks, like Professor_de_la_pas seem to use them often and effectively. I'll keep an eye out for the subs that allow them to use those flairs.
