Hi! Just installed K2, so please bear with my ignorance...

1. Created a category: NEWS
2. Created subcategories EVENTS, CLASSES, SHOWS.
3. Created a few items for each category, plain text items with 'read more...'

I would like to display a title of the subcategory, and below it the intro of each item with the read more link.
I have done that, okay, I guess. What I cannot accomplish is to organize the listing as a category blog, with 2 articles side by side (2 columns) for the leading, 3 columns for primary and secondary and may be 4 col for just links... Everything comes out in a single column. Also, what makes an item leading or primary,or secondary? Just the order and the count? Or is there a way to flag articles and make the primary, or leading ?

Hope I am not asking too much...

Thanks!
Enrique.
