CMS Is a site INTRO page bad for SEO?
 

I want to add an html intro page that is only images, and a small swf video in the middle.. if you want to see it in action, just ask and I can show you so you can get a better idea.

If I enable this does it have any impact on the SEO of my site at www.brotherhoodofgamers.com? How would it affect my advertising and SEO?

Thanks.
