sorry my English is bad. I found the file comprofiler.html.php. I looked into it before posting on the forum. But it is in comprofiler.html.php I can not find the line to edit

It is on line 439 , change $user->username to "Some text you want" (include quotes!) . But I do not recommend doign this, as this may break something.

Great ! Thank You , works very well !
must also change the class comprofiler.class.php
