„Read more” problem

Hi,

Is there a way to add the “read more button” for the pages that have more posts that can be displayed ?

For example I have a category with 50 articles. I chose to display only 25 in a page. is there a way to display the “read more” button so the user can also see the rest? Because there is no way someone can access all old articles.

Example: http://www.dota2romania.com/stiri/ (there are much more than 25 articles there)

P.S. or maybe “page 2” would be great, not necessary “read more” button. Any of the 2 would be great.
