Using Fetch is really easy! We'll run through a sample ftp session where you will connect to NetRunner to upload your Homepage.
Open up Fetch and enter in ftp.netrunner.net as your host. Then enter your username and password. That should automatically take you to your home directory. Upon arrival you will want to select (click on) the "public_html" directory/folder.

To upload a file simply choose "Put File" and you will then have a box open allowing you to select a dopcument to upload. When the correct document is in the box, just send it along. "Raw Data" should be your selected format. If not the files will be unreadable. "Raw Data" works for everything else too, so it's the recommended setting.

And just use the reverse steps to "Get" something from our server to your machine.
