  Indeed, I agree with both Jon and David that the recommendation of

  I would think this ushers in Linnaean-esque enjoyment, which mandat=

  I have a simple observation: PhyloCode is about defining names and
linking them to clades firmly ... it should NOT be about how to name
names. That way runs to the ICBN/ICZN, and I was under the impression=
, at
least from talking to Michel and Phil, that the PhyloCode was to run
concurrent, not try to replace, the existing codes. My real enjoyment
would be to get the current codes to recognize ALL levels of taxa, an=
d to
make the use of ranks faculative, i.e., optional. This will not likel=
happen, but it would be easier to work with all the codes together.
