CMS Made Simple Forums

I have only been working with CMSMS for a week or two so I have some really basic questions. I did check the website, but I have found most of the documentation lacking.

If my template is a tpl file and not listed under the templates section inside of CMSMS , then how do I associate a style sheet that is inside of CMSMS to my .tpl file?

When I modify a template inside of CMSMS how do i Specify the action of a form object ?

Thanks in advance.

Why storing the templates in files? Because of editor? Try Template Externalizer.

I don't understand the second question.

How Do I call the processTemplate function on a template that is not a TPL file?
