The 'anonymous' part indicates that you don't need to have an account on the system you're receiving the file from - its a public file server. Offering a public file server on your own site has many strong points in its favor - although you can make files available on your web site through HTTP, ftp is much faster and more reliable than HTTP for transferring files, and has additional features, such as the ability to resume a failed download. Used correctly, anonymous FTP can become another valuable part of your site design. Extra FTP Logins - Chances are that you wont be the only person involved in the design and management of your web site, or you'd like to give some space on your server over to a friend or associate. Having extra FTP logins to your site means you can give people access to directories on your site, so they can manage their portion of the site themselves, without giving them access to your home directory or control panel.
