I just started a blog and want to adjust the summary of a post so that it shows the first paragraph. I want this to be dynamic for each post, not a fixed length. Is there a function I can use that allows me to do this?
I've tried the <!--more--> tag as found in this support question(http://wordpress.org/support/topic/how-do-i-show-a-summary-of-posts-on-the-home-page-and) but it didn't work correctly. I was also going to make some other changes stated in that link but I couldn't find the_conent() or the_excerpt() functions in index.php. Any help would be great.
My site is criticalchance.com if you need to look.
