Hallo,

can i limit the post excerpt length (text in the "grey text") automaticly with a setup in the template (functions.php)?

I use the "Auto Blogged" plugin for the content. It displays an identical text in the excerpt section (grey text) and "black text" section. I can´t different the sections in the plugin setup.
