As discussed, I'm making the following changes to names in the Pied UI to match names in Overflow: Loci Name Overflow Name ========= ============= Workspace ---> Network Locus ---> Node Loci ---> Nodes (or Pied, depending on meaning) Connector ---> Link Composite ---> Subnet Brad, I hope the use of "node" does not cause any problems. You mentioned the conflict with DOM, but I'm assuming Pied is far enough removed. Jeff -- J.W.
