Pligg Filebrowsing integration

I use Pligg + Fckeditor through Replacement of Textarea.
Everything works fine but all users upload your files to '/userfiles/' folder. I would like to create their own "home" folder for each user.
How to do this?

All I have is $current_user->user_login php-string for resolving current-user username.

I found doc http://docs.fckeditor.net/FCKeditor_2.x ... ntegration (do I need it?)
but it is very difficult for me.

Help! If you have expirience with Pligg.
