hey Rocky,

in PHP you can define classes, and typo3 uses them massively.
If you want to us ethe variable $usrnm throughout the object
then assign the variable like this:

$this -> usrnm=$GLOBALS['TSFE']->fe_user->user['username'];


Also don't forget to check if a suer is logged in at all and if the 
fe_user array was filled.


I could also strongly suggest reading up PHP, classes objects, variables and
variable scopes in PHP since this was more a PHP question then a TYPO Q.


good luck with the extension,
Ries
