On my blog: http://benintendo.wordpress.com I want to get a summary for certain posts because they are too long with the pictures and all but when I select 'For each article, show: summary' and I fill in the optional summary, I don't see the summary on my frontpage... Do I need to use some sort of code?
Since you're on WP.com, you can edit the template code. Normally to show only summary, you use the_excerpt instead of the_content. Most theme automatically do this if view category or archive. Using <!--more--> would do
