In a nutshell, here's the barebones HTML code that you need:

<FORM METHOD=POST NAME="subscribeme"
      ACTION="http://cf1.netmegs.com/cgibin/formmail.cgi">
<textarea name=mesg cols=30 rows=4 wrap=virtual>
<input type=submit VALUE="Send Us The Message">
<INPUT TYPE="hidden" NAME="recipient" VALUE="techy@charityfocus.org">
<INPUT TYPE="hidden" NAME="subject" VALUE="Website Submission">
<INPUT TYPE="hidden" NAME="email" VALUE="nobody@domain.com">
<INPUT TYPE="hidden" NAME="realname" VALUE="Auto FormEmail">
<INPUT TYPE="hidden" NAME="redirect" VALUE="http://charityfocus.org/cf/thx.html">
</FORM>

Please also remember that this script is only for use with cf1.netmegs.com and should not used anywhere elsewhere. It is likely to change without any notice. You should install your own formmail.cgi script if you are working with another domain (more on setup and as always, you can always email us). This is only meant to serve as an example and to provide functionality for the staging area.

Also note that you can also just use the mailto tag (although not as robust as the previous one):

<FORM METHOD=POST NAME="subscribeme"
      ACTION="mailto:nipun@charityfocus.org">
<textarea name=mesg cols=30 rows=4 wrap=virtual>
</FORM>
