Thanks in advance for any and all help on this topic. I have set up an FTP server that works pretty well via PureFTP. I want to do the following and have been unable to find any information on how to.

1) limit users public_html folder size. Basically users(teachers) will put their web pages here and I want to limit how much they can store.

2) When they log into the server, I want the default directory to be public_html, and not their home directory.

Is there a way I can do both of these. Thanks again in advance.
