Hiya Ghost Hand!
Maybe I'll give you one of my hands (in friendship :)).
So...to change your words under your name, you do the following things:
1. Go all the way up to the top of the webpage. There, you'll see the words "Welcome Intervening Ghost Hand", "Notifications", "My Profile", "Settings", and "Logout".
2. Click "Settings".
3. On the left side of the webpage will be three tables, titled "My Messages", "My Subscriptions", and "My Settings".
4. Under "My Settings", click "Edit Profile".
5. The big table next to your messages, subscriptions, and settings will have changed. Now it says "Edit Profile Intervening Ghost Hand".
6. Right under the "Registration Required Information" section, is a part titled "Optional Information".
7. Go to the "Custom User Title" section, and it will say "Your current user title is Junior Member".
8. Below this and the info that tells you what the title is, there is a blank space. Fill this space with what you like, such as SUPER AWESOME PERSON.
9. Lastly, go all the way to the bottom of the editing table and click "Save Changes".
10. DONE!
Apologies if the text is a little long. My web protection system restricts me from inserting images into my posts... :P.
