Easier said than done! I read from Newest Nodes, and when visiting a new top-level SPOW or Meditation, it doesn't tell me whether it still needs approval. They all look alike, one way or the other.
You need to go to User Settings and turn on the "Approval Nodelet" for non-frontpage nodes. (For those watching who haven't reached level 6 yet, you can't turn on the "Approval Nodelet" yet.)
