Proftpd configuration question

Hello all,

I have setup Proftpd following the instructions provided in the following thread:

https://www.experts-exchange.com/questions/20643880/ProFtpd-accounts-setup.html

This works great, but being a newbie to Linux, I was wondering how I would accomplish a couple of things using the configuration given:

1. I would like users to be able to create subdirectories in their home folders, but the config given doesn't seem to let them do that. How would I grant permissions to do so?

2. Given that the permissions are not managed within Linux, how would I setup another user so that they could access and existing proftpd user's home folder in read only mode?

If someone could help me out with this, I'd appreciate it!!

Thanks,
Kang
