Could someone explain to me the FTP structure that DH has set up here? I have more questions, but with my knowledge (or lack there of) I don't exactly know how to word it.
Okay, well that was basically no help to me at all, so I'll try a more direct approach. How can I give an ftp username access to only one directory? Meaning they can't see the logs folder, the yyyy.com/.net folder or the mail folder.
Well, you can't really do that. You can, but it will cause you problems. You would make the user the owner of the directory (in the path to that directory) to give them and only them access to that directory. It works better if you set up a subdomain for them.
