BuddyPress.org

Hi All, does anyone know a plugin or some code to limit the length of activity posts in groups. I have created “companies” (groups) on my site and as you can see, some of them are lengthy. I would much rather it link to the full page than display it all in the activity stream. It would be great if it just showed an excerpt with the option to “view” (as is built in to Buddypress) when the post in longer than X amount of words etc
