How can I obtain a flair and what is it?
«Flair» is a message or a logo that appears beside the username and referred to as a user flair. Each subreddit possesses of a unique flair which can be customized by means of special mods.
To obtain your own flair, you have to find the «Show my flair» tab situated on the right side of the sidebar. It looks as follows. However, if you feel like modifying it, the edit button is located alongside the username, just click it. (In case there’s none, you can only obtain the flair from the mods in the subreddit.)
