Every time you create an account, you are creating a full-featured hosting account.

You can access your CPanel accounts just by following http://hostinpakistan.com and then click on CPanel. Enter your username and password to login.

If your domain is not active yet then you can access your website by visiting

http://www.hostinpakistan.com/~clientusername/

Note: the tilde (~) is NOT a typo. This is required in order to be able to reach the account.

The mail and FTP settings should be the same IP that you find in your setup email, or, post-propagation,  your clients may use ftp.domain.com and mail.domain.com.
