[SOLVED] Mixing static content + excerpts on home and category pages ?

Hi there,
I am working on the web site of my bike club and would like to be able to mix static HTML content and excerpts on both the home page and *some* category pages.

I am new to all this WP thing, and I must say that I do not know where to start.

I was thinking that I would put my static HTML content into files that I can then include, but that is the only hint I do have.

Here might not be the right place to ask this question (as I am not sure if it is a theme question or a WP question), so feel free to point me in the right direction.

Any pointers will be much appreciated.

Subsequently I might want to display exerpts on the home in two columns (I saw a sticky about that) en have different number of excerpts for some categories, but we will cross that bridge when we will cross that bridge.

Thanks in advance for your help.

Jean-Michel.
