I just upgraded to MT 4.3 which also upgraded Action Streams automagically behind the scenes. It appears that MT itself now creates an action stream whenever I create a new blog entry or someone comments on a blog entry. Is there any way to turn off this new behavior? Under "Other Profiles" I see all my other Action Streams but nothing MT related.
And on a related note, anytime someone comments on a blog entry, the corresponding action stream says "$blog_owner commented on $blog_entry" instead of the person who actually commented. Is this configurable or a bug?

Hacky workaround. I modified /plugins/CommunityActionStreams/config.yaml and commented out everything I didn't want to automatically publish. Still can't find anything in MT itself either in the community preferences or elsewhere to configure Community Action Streams.
