Insert Interspire Email Marketing Contact Form Code into WPMU


Using WPMU 2.8.4a

We use Interspire Email Marketer as our Email Marketing application. We need to insert the html & js code generated by the application into the Contact Us page. Is there a way to insert this code into WPMU of the main site?

Also, what contact form plugin should I have to install so that all blogs are able to see and use?
