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!
Visited my personal details but cannot view the custom title box below my avatar. Is it the "about you" ?
