BuddyPress.org

For Group invitation I know it’s in the bp-groups folder in BP. The file bp-group-notification.php

at the bottom you’ll see:

‘One of your friends %s has invited you to the group: “%s”.

To view your group invites visit: %s

To view the group visit: %s

To view %s\’s profile visit: %s

I think you just need to replace the %s with your website or whatever you’re talking about.

Remember to back up that file before editing. I dont’ know PHP so I don’t know what it will do.
