some menus have a message menu in it and you can select a custom text

1. I use GTA5 on PC, so I use the "Menyoo" type of menu but you can find all of the menu by doing a search on Youtube

2. You can use different font types and large text such as:

Clingy [ I used the Comic Sans MS font]

Clingy [I used Courier New]

All you have to do is when you are making a topic or just a basic reply:

Step 1: Use any font, (I'm going to choose Comic Sans MS)
- Go to the message body
- Click Font Type
- Click any font (I'm choosing Comic Sans MS)
It should come out as
[ Register or Signin to view external links. ]

Step 2: Click the size you want to use. (I'm going to choose Large)
- Go to the message body
- Click Font Size
(This should be with Step 1)
It would look like:
[ Register or Signin to view external links. ]

Step 3: Type in the text box (I'm going to type Clingy)
It should look like:
[ Register or Signin to view external links. ]

Step 4: Hit Preview to See if it right
Clingy (That how it came out in Preview)

Step 5: Hit Submit

Boom! You're done

I hope I helped <3
