How would you make a spot were the player would right therer name and it would show all the rest of the writing would refer to him as in andrew did this...

Under the "Other" category, check out the "Enter next command into string variable" command.

BUt hwo would you make a IF player does that then...?

As you would expect, after your "Enter next command into string variable" command, you can use an "if" script. In your "if" script you can add a condition to compare the string the user just entered. Or you can use a "select case", check out the tutorial for info.
