I haven't looked into it in any detail, but I suspect you could use an
augmented Schulze method where the function d_v(i, j) (being the
function which normally returns 1 if voter v prefers candidate i to
candidate j and 0 otherwise) returns 1/n where v's preference for i =
v's preference for j, with n being the number of candidates for whom v
shared this preference (including i and j).

Having said that, I don't know what counting system MemberDB uses at
the moment...
