ftp user with gid www-data

[comdi]

Hello

Is there anyone with the same problem?

My ftp user had uid vuxxxx and gid vuxxxx
- The directories and files created by ispCP had uid vuxxx and gid www-data

This makes problems if you use an CMS (typo3) it cant show the files
i had upload with ftp, because they have a wrong group!

I had searched for proftp hacks, but I dont find some working one.

Is there a way to change something in ispCP to create ftp users with the group www-data?
I'm surprised that I cant find any thread about that problem in VHCS or ispCP!
