flexo archive count

hello.

i added a page (fed by a certain category of posts only) that is hidden from the menu and from search and archive pages, to create a kind of “how to” for the web-page owner.

To exclude it from search and archive was easy, i would also like the articles written in this category (to this page) to be excluded from archive count. I use flexo archive widget. Any idea ?

Thank you ??
