Showing text description on a Category page along with the documents...

[ROUBOS]

Hi,
I have created my categories which in turn have document.
Now a category page (linked to a menu) displays a blog of documents that belong to that category.
When editing the Category details though, there is a text entry for a description. What ever text I place in that, does not appear on the webpage.
How can I do it? I want to have some text, and then the blog list of documents of the category..

hope I'm making sense.

To understand you much better i'll give you an example with my site on Greek.

Here : http://www.texnomesitiki.gr/dunami-tis-gnosis/
is six different categories  on which each description we will find it when we choose one of them.

Take a look e.t.c in category "Φορορολογικά Θέματα" ( the last one ) it's description is here : http://www.texnomesitiki.gr/dunami-tis-gnosis/forologika-themata/ ( at the top of the page).!

Can you find it on your web page ?

What I'm getting wrong is the display method of things. (I also speak and read greek if it's easier for you, I just write faster in english )
OK
So I create a Section > "Structures"
Then I create the Categories > "houses" , "commercial buildings", "hotels" etc (belong to the section Structures)
then I create the content items and add them under specific categories.

How do I go about displaying them? Whats the best way. Blog or table? I want to have a page linked from the menu, for example "Houses" displaying all the houses in one page with a small description, and when clicking on the title to display the content in full....
look at this for example http://www.isternia.net/blog/politismos/artists/

EDIT >> At the moment I have my Categories as a Type: Blog of Categories....

I was looking at how Links works. Kind of what I am looking for. So should I be looking at setting this up using a component instead?

PS. To change the type, I need to delete and start over?
