BuddyPress.org

I am looking to customize all email content, activation emails as well as notification emails. I am using WP multisite with buddypress.

Currently when an email comes through it looks like this:

New comment on your post “My Comments Work”
Author : USER (IP: xx.xxx.xxx.xxx , )
E-mail : USER@aol.com
URL :
Whois : http://whois.arin.net/rest/ip/xx.xxx.xxx.xxx

Hello

You can see all comments on this post here:
http://domain.com/2012/12/19/my-comments-work/#comments

Permalink: http://domain.com/2012/12/19/my-comments-work/#comment-6
Trash it: http://domain.com/wp-admin/comment.php?action=trash&c=6
Spam it: http://domain.com/wp-admin/comment.php?action=spam&c=6

I would like to get rid of most of the content in this email. Any ideas on where to locate the files?

Thanks
