The Press Articles used in WAG-MOD websites have been developed as an easy interface to create a web page. The WAG-MOD Press Article is a versatile tool, but you may also use FTP to get other content to your site so that the Press Article editor can interact with that content.
Webs-a-gogo also offers "self-managed" webspace for advanced users who do not use WAG-MOD. When this is the case they must upload data to their websites using the FTP process. This HELP explains the use of FTP.
