Displaying multiple article excerpts

Hello,

I’m having an issue with being able to display multiple article excerpts on my category subpages.

For example, once I click on the “Attraction” category, only 2 articles excerpts will show up, even though there are 3. If I increase the “posts per page” option under my wordpress admin control panel, then it will display more excerpts, however it will also display more articles on my home page, too.

I do not want this, I want to limit the articles on my homepage to 2, however, display as many excerpts as possible on my category subpages. How would I go about separating these two features?

The website is http://www.take-20.com

Thank you,

Rahul B.
