I have a strong preference for the use of teaser text. When I create a post I would like to show the title and a teaser on the frontpage. The teaser should be automatically pulled from the beginning portion of the item content. I really dislike the broken sentences solutions. I would much rather see the full first paragraph or an excerpt if that is available. How do I get WordPress to make this happen?

I decided to buy a nice theme from RocketTheme, the next challenge is figuring out how to work with it.
