[Plugin: Simple Facebook Connect] How to limit the number of characters in the post snippet

oops, clearly that should have said fb not fp :p

The sfc_excerpt_length filter will let you control the number of characters it will read in order to produce the published text. It defaults to FB’s maximum, which is 1000 characters.

add_filter('sfc_excerpt_length','my_length');
function my_length($num) {
  return 50;
}

Put that in your theme’s functions.php file or in a plugin or something.
