Question: Sharing access with other CP users


I created a new SSH/FTP user for another person to manage a certain doman I’m hosting with DH. I also created a new CP user for him to be able to manage this domain.

My question is, can I give his CP user access to create new fully-hosted subdomains for that domain, under my account? Right now, his CP says he has “-1 domains left” and “0 subdomains left”, so he can’t create subdomains himself.

Also, can I give his CP user the ability to create FTP accounts for his domain? How about MySQL databases?
