title: Wordpress - How to limit characters to show at Feeds?
body: <p>In wordpress, there is settings for the feed to show Summary or Full. I want to show only content summary at Feeds. But the default summary is still too long for me. And there's another way to add excerpt at each of the post. For that option, I can't use it either because I am running multiple author blog and most of the people don't know how to add excerpt and my posting form is custom form which is not allowed to add excerpt. I tried to search at google and wordpress plugins, but still haven't get any clue yet.</p>
  
  <p>Is there anyway to limit characters at feed display ? Or is there any plugin out there ? Like at feedburner, I can activate summary feeds and limit the characters. </p>
  
  <p>Please kindly help me out again. Thank you.</p>
