hi,

well, first of all, there no detailed ALBUM view but detailed ARTIST view (I know it can be confusing: on detailed artist view is where you see the detailed albums )

the best you can do is to check wheter the user is registered or not on the file

/components/com_muscol/views/artist/view.html.php

if I'm not wrong, the variable containing the view will be

$this->_layout

so you should write somewhere something like...

if($this->_layout == 'detailed'){
//your user checking code here
}

hope it helps

Germi

Thank you :-)
