On my computer, Starcraft can display 11 lines at a time. If you try to display any more than that, it will just display the last 11 lines.
Your computer may be different, I'm not sure. It's easy to test, though, just go into a Starcraft game and type a bunch of lines until it doesn't display any more and count the lines.
So for the credit intro trigger, you can do this.
First make a template so it's easy to see what line you're working on:
1
2
3
4
5
6
7
8
9
10
11
Put that into the "Display Text Message" field and you've got your template. Add your name wherever you want it. If you put it on the 6th line, that should put it in the middle of the screen, vertically. To make it horizontally centered, copy and paste this character: before every bit of text you want centered.
Make sure you delete the numbers on each line when you finish with the trigger (obviously).
You'll need to use a "display text message" trigger just like that one for every different color change you want. Each one will need to have a different color code symbol. Look at the end of this post for the basic codes.
Keep in mind that if you want the text to look like it's flashing colors/moving/changing, you need to insert a "wait" action between each "display text message" action otherwise all the text messages will display instantaneously and you'll only see the last one.
To make the text look like it "moves", add spaces before/after the letters, and put it on different lines. The concept is simple, it just takes trial and error to figure out the right timing and placement.
Here's the basic color codes, these are by DI of Campaign Creations:
