I'm using all the recent updated plugins for buddypress 220.127.116.11, wordpress 3.3.1 and installed this BuddyPress Block Activity Stream Types 0.5.2
listed new_member in the provided section, saved settings, created a new user as any new user would - from the front end - and it still showed "test user 4 became a registered member 12 minutes ago"
checked the database to make sure new_member was the correct type and it is.
What else do I need to check?
The only plugins I'm using are...
BP Profile Searc
BuddyPress Block Activity Stream Types
WP PHP widget
