which file in ataualpa makes what?
I am going to make some own template-pages for my menulinks.

I think I should copy the right content from one of them but don't know which?

You would generally start with index.php for something like that.

Thanks!
Is it best to start from scratch or can I use some start codes to start with?

Like I said you would start with index.php, rename it and add the necessary code per the WordPress codex to make it a page template and edit as you wish.

ok
Thanks to you
