We've added a new feature to the site. You can now display a 3D flag by your username so others know what country you're from. We have a diverse group here and thought it would be a fun and helpful feature. However, we realize many users wish to keep their anonymity so you have to opt-in.
For current members simply go your Profile Settings (Edit Profile) and scroll to the bottom. There you can set your country flag.
New users will have the option to choose their flag upon registration.
