Summary and conclusion: (1) Multiplicity - PHOBOS have performed complete charged particle multiplicity measurements for Au+Au, Cu+Cu, d+Au, and p+p collisions, System size dependence, and 'Complete' pseudorapidity distributions; 'Universality' compared to elementary e+e- collisions; and (2) Midrapidity multiplicity - Factorization of centrality and energy dependencies; (3) Limiting fragmentation - extended longitudinal scaling - Seen for Au+Au, Cu+Cu, and d+Au, Also observed in flow observables; (4) Total charged particle multiplicity - N{sub ch}/N{sub part} constant with centrality, (5) Future - Finish up many analysis and reviews.
