Perhaps there should be a new Budget Committee of the board, with a similar
composition to the Audit Committee in that the membership would include
some WMF board members and some community members. The Budget Committee
could do FDC-like reviews of WMF's Annual Plan proposals each year.
I personally would prefer to avoid the "core" and "non-core" division
the WMF budget, since I feel that the whole budget and the performance of
the whole organization should be reviewed at least annually. The Budget
Committee could look at the big picture in more depth than the Board as a
whole and the FDC would have the time to do.
