posting from a message via a cgi script

Hi, All,

I wonder if anyone can give me advice on posting from a message via a cgi
script.

I'm using Mhonarc 2.3.3 to setup a newsgroup. When one browses a message
and want to reply it immediately via a web form,(ie. put a "Reply" button),
a cgi script may be necessary. I have composed such a cgi script to post
mail form (or send email). But I don't know how to link this cgi with
Mhonarc to work. And I'm not sure how to set the resource file. 

Thank you for your help.

W.J.
