That's why it's called a custom title after all! What is a Custom Title? I'm glad you asked! - Just to the left of the posts you see the avatars, just below the avatar is the username, and just below the username is the custom title. How do I set my Custom Title? - It's easy. Go in your personal details (link) and you'll find it just below the avatar. What should I use it for? - Well, that's up to you. Something about yourself, something random. You've got to keep it short though, it only accepts 50 characters. Just keep it clean!
