So, I have the blog and on the main screen my latest posts. I have a menu with categories, ppl can choose categories at the top and read articles belong the chose category. My problem is that when I choose a category I see all the posts in full there, while I want them only a few line long texts. The problem is that the current way only one post in the category takes all the page and ppl need to scroll down and down and down for older posts. If I could make the posts appear there not in their full length then that would be awesome.

I show you an example: this is how my works: hirpotlo.wordpress.com
This is how I want it to work: http://rosszabbikblog.wordpress.com

I hope someone can help me in that. Thanks in advance!
