Is it a Posts or Presentation Page choice?

Hi – I recently switched my blog site over to the Mantra theme …I’m loving the flexibility of Mantra and its ease of use for a self taught non-techie like me. But I can’t seem to find a way to make my previous blog posts visible. As I’ve read through some of your How To support pages I’ve gotten the impression that if I choose the Presentation Page option I can’t have my archive of blog posts show.

If that is correct, do I copy all of those old, yet still valuable and relevent, Posts over to a new page that I create called, say, Gwen’s Blog? Or is there some other work around that isn’t obvious to me?

Thanks for such a richly diverse theme that is pretty danged easy to use. We need more like this!
