Blog page shows complete posts

Hello,

I’ve been using the Aqua theme for a few days now and I like it a lot. So first, I would like to say congratulations on a job well done. Good looking and functional corporate themes are hard to find.

The only rock in my shoe is that my blog page is showing every posts complete. The demo version I had seen only showed exerpts. What do I need to do to correct this?

The page is here if I’m not being clear enough: http://hautevoltige.net/publications/

Thanks,

Mickael.
