sparkicks, you need to have an SMTP server and a POP3 or IMAP server setup setup on your machine. SMTP is Simple Mail Transfer Protocol (it might be Send Mail Transfer Protocol, i forget which), its how you send emails to other people. POP3 is Post Office Protocol version 3, its one way you can recieve emails, IMAP is internet message access protocol, its another way to recieve email. If its true that Macromedia Dreamweaver can create PHP scripts (never used it beofre), you still need to install PHP on your machine. Go to
http://www.google.com and search for a free "POP3 server for windows" same with SMTP and find one to setup.
