Silly me , I was wondering what happen to you . I vote that your commit
priviliges should not be taken away by the "Dark Side" of core and
should be re-instated.
Also wondering if this is perhaps a good time to split up FreeBSD
along commercial / professional lines -- we can leave the silly
core group along and proceed forward with a business model.
Cheers,
Amancio
