Query: Experimental Status of Leptonic Ds Decays   The measurements of the leptonic branching ratios BR(Ds->tau nu) and
BR(Ds->mu nu) are reviewed. The values of the Ds decay constant fDs derived
from the measurements are updated and a world average is calculated taking into
account the large correlations between the measurements
