Basically, how do you change the bp_activity_content_body() to excerpts for the activity stream. I used a modified version of this: http://codex.buddypress.org/developer-docs/custom-buddypress-loops/the-activity-stream-loop/

I’ve tried shortening it with PHP, since I can’t find an excerpt template tag, but wasn’t successful:

<div class="activity-inner">
<?php

$chars = 125;

$excerpt = bp_activity_content_body()." ";
$excerpt = substr($excerpt,0,$chars);
$excerpt = substr($excerpt,0,strrpos($excerpt,' '));
$excerpt = $excerpt."...";

return $excerpt;

?>
</div>

Any ideas?
