Well HTML forms are basically all there are, unless your site is flash. But that's just to make the actual form that one sees, with text boxes, etc. To validate (meaning to make some inputs mandatory) you'll need javascript, and to have it emailed to you without use of any email programs on their system, you'll need to use a serverside scripting language, i.e. PHP, VBscript, Java (servelets or JSP) or some kind of cgi script. What language does your host support?
