You can add FTP users from your hosting control panel. Simply FTP access, and then Add FTP account.
Enter a username and password of your choice, and if you would like the user to only be able to use a certain amount of your web space enter a figure into the Disk quota field.
Once you have created your login, you will need a program that allows you to login and send files. A popular free FTP program is called FileZilla. Once installed, start up the program and enter the following details in the top bar:
- Host: ftp.gradwell.net
- Username: as set by you
- Password: as set by you
- Port: leave blank
