Is it possible for this script to simply replace the text in the effected text box to the computers User ID Name (Mac) or User Account Name (PC)? If possible.

Code:
var textFrames = activeDocument.textFrames;
 * * *for (var i = 0 ; i < textFrames.length; i++)
 * * * *if (textFrames[i].note == "UPPER FORDDOC NAME") {
 * * * * *var frameName = textFrames[i].contents ;
 * * * * *newFrame = frameName.replace (/(.*-.*-.*)-(.*)/, "$1$2") ;
 * * * * *textFrames[i].contents=newFrame 
 * * * *}
So when I run it on my computer it will see my User ID Name which is BLAU then put that into the text box in Illustrator but if JOHN DOE ran it on his computer it would put JDOE (His User ID Name (Mac) or User Account Name (PC)).
