Hi,
I have no problem with a quota system and maybe we should address this.
The reason for not installing a larger drive is, I believe, that
backups then become problematic. However, maybe we could have larger
drives but reduce the backup load by backing up only certain
directories or files.
Certainly we can remove a lot of inactive users.
Cheers,
Douglas
