In order to process submissions received from web forms you need to have the following things completed :

Install Web Form Toolbox on your computer.

Have one or more web forms placed on a web server.

Have a CGI-script to process web forms installed on your server.

Configure Web Form Toolbox to work with your web forms.
 
Here is a sample of the installation of a web form and CGI-script on a free web server called Netfirms. First, you need to open an account at http://www.netfirms.com. Follow the steps below :

Go to the Netfirms website and select the option Signup -> FreeName Subdomain (http://www.netfirms.com/signupfree).

Enter your company name (for example, eglum). Your website address will look like this: http://www.eglum.netfirms.com

Download a CGI-script from our site (click here to download a free script).

Place this script in the cgi-bin directory on your account at the Netfirms server, using an FTP.

Place the web form to which the program will be configured on your website at the Netfirms server, using an FTP (The web form configuration is described in detail in the User Manual).
Of course, a CGI-script and a web form can be installed on any other server, and not only on the netfirms.com
