In supersymmetric models with R-parity violation, scalar neutrinos \stackrel\ifmmode \else \~\fi\ensuremathν may be produced as s-channel resonances in e+e^\ensuremath- colliders. We note that within current constraints the scalar neutrino may have a width of several GeV into bb and be produced with large cross section, leading to a novel supersymmetry discovery signal at the CERN collider LEP II. In addition, if m_\stackrel\ifmmode \else \~\fi\ensuremathν\ensuremath≈mZ, such a resonance necessarily increases Rb and reduces AFB(b), significantly improving the fit to electroweak data. Bounds from B meson and top quark decays are leading constraints, and we stress the importance of future measurements.
