BuddyPress.org

Hi all. I’d like to know how I can change the text in the activity stream from so and so “wrote a new post” to something else. I’ve found a few instances of that text and changed it, but the effects do not show up on my site. I read that it can be found under, bp-blogs/bp-blogs.php, but I can’t find that folder or file. I’m using the newest version on buddypress and the template pack as well. I’m also using a premium theme, which is compatible with buddypress, called FunGames. Thanks for any help.
