N2 - I report final CLEO-c results on the purely leptonic decays of the Ds+ → ℓ+ν, for the cases when ℓ+ is a μ+ or τ+, when it decays into π+ using 314 pb-1 of data at 4.170 GeV. I also include preliminary results from the τ+ τ e+→ channel using 195 pb-1. Combining both we measure fDs 275 ± 10 ± 5 MeV, and fDs+/fD+ 1.24 ± 0.10 ± 0.03.
