Very Urgent Wordpress problem

hi we created this website:? <[login to view URL]>? with wordpress. for every category (study / abroad ..etc) we made a separate Wordpress installation in a subfolder. on the frontpage, an article+picture are loaded from each of the categories. currenty this is just a static page, to show how it should look like. however, we need that ? the frontpage will load the articles + photos from the specific subcategories. it should be finished within hours. please let me know - if you can directly change it - proposal again, it is very urgent!? thanks,
