i admit im a complete amateur when it comes to building websites. I went on
template monster.com and saw a template that I loved. I bought it and began
using flash to edit it. Im ok experienced in Flash but abd at actionscript.
Anyway Im still in the building phase of my website when I start thinking to my
self, How am I going to be able to let users register as members to my website?

I go online and learn that im going to need a content managment system which
my webhost aready gave me. I also know that when im done editing my Flash
website I need to Publish it in HTML. Heres where I get lost, after I publish
the HTML in Flash and say I open it up in Dreamweaver.....I cant do nothing to
edit it in dreamweaver its just an SWF File.

What if anything do I need to do to let open source software work with my
Flash website?

noone can see me way down here

Hi,
If you are going to do your site with Flash, then I do not think it is
possible to use Opensource with it, because Open Source CMSs is actually work
on a template structure that is turn your HTML code to PHP and embed in it PHP
codes that call external functions (Modules). If you like to use PHP with
Flash, you will need to do it manually without relay on an Open source CMS.

Hope this helps
