Front Page SEO - Global Meta only on Front Page

Hi All

mambo 4.5.2

I need to have unique Front Page meta descrip and keywords that are not shown on any other pages

The prob is that the only way to put meta content on the front page is by using the Global Meta stuff in Global Config, but then this is shared with all the other pages.

Is there any way that the Global Meta content can be EXCLUDED from all pages except Front Page?

Like, "show on Front Page only"

The Front Page must be:

http://www.mysite.com

I can't make the "Front Page" a sub page, like a static page, cuz that would kill my PageRank.

This would really help me. I've spent months learning mambo, learning template stuff, sef, the whole thing, but this issue has almost stopped me cold. SEO is critical for me.

Many thanks
