Where do I go to post about Adobe Experience Manager (AEM)

I  have an external js file.i called it in main.html like <script type="text/javascript" src="relevent path to the file mentioned in the topic" but cant load it which path is  /apps/appname/components/structure/page/x.js in AEM publsher.In AEM author it is directing to the related js file.Purpose of doing this is i have a java script code for eloqua form submission which is inside main.html.because of eloqua js is inside main.html as internal js it is affecting to page load time.so i have to put that js as an external and call.Either this way <div data-sly-use.page="${'x.js'}"/> is not working because of that eloqua js is returning nothing.
