2	TARGET	Name of the target frame where the form is to be presented.
3	METHOD	The method by which the browser will send the form's data to the server for processing. This attribute can be set to "GET" or "POST"; the default is "POST". With the POST method, the browser sends the form's data in two steps: it first contacts the server specified in ActionSub and, once contact has been made, sends the data in a separate transmission. The GET method contacts the server and sends the form's data in a single transmission: data is appended to the URL Uniform Resource Locator - a web address.  in ActionSub, separated by a question mark. In general, use POST if the form has many fields or has long text fields, or if security is an issue. Use GET for forms that have only a few short fields.
4	ENCTYPE	Specifies the encoding to be used to send the data back to the server. Can be optionally set to 'multipart/form-data' or 'text/plain'. If you do not set this attribute, the standard encoding format is used.. You should specify 'text/plain' if the form is to be sent to an email address rather than to a server (the mailto URL Uniform Resource Locator - a web address.  would be specified in ActionSub).

Attributes defined in the aClass parameter are applied to the FORM tag.
