I have a website that has many static pages for the most part. They get mild changes from time to time but mostly static.

I'm aware that Caffeine likes active updated content. So...

1.Since we have an active forum on the site, will that active status bleed over to the static pages and make it so they are valued as active?

2.If not, how much do those pages need to change from time to time to appear active and fresh. Not necessarily meaning daily but more like meaning how much on the page. A sentence? A paragraph? Any ideas?

Thanks, I'm still trying to grasp how Caffeine works so be easy on me
