SOLVED !!! Editing code

Hi, how do you edit the html/php code - for example on the agent registration page it currently read:
"Please fill the bellow form. Notice: (*) are the mandatory form. "
It would read better in English as "Please fill in the form below. Notice: (*) are the mandatory fields to complete"

I cannot find a way of editing the code.

Thanks in advance.

I have found an answer myself.
It is item #617 in the list of fields in the manage translations pages.

SOLVED!!
