<div style="">Dear CPN members,
<div><br>
</div>
<div>Only five of us have voted on the set of proposed changes I sent the listserv on Monday (attached again to this message). I suggested today as the deadline, but since less than half the committee has voted, this was clearly insufficient time. Please
send your vote by next Tuesday (Nov. 6), election day here in the U.S. The following people have NOT yet voted: Anderson, Andres, Gauthier, Joyce, Marjanovic, Olmstead, and Tank.</div>

<br>
This is a worthwhile discussion that should definitely be continued, but I realize now that I made a mistake in even including the glossary definition of Taxon in this round of voting. This was the one entry in David's Sept. 29 set of comments that I suggested
we postpone because it will take a while to work through the many uses of the term "taxon" in the code. In my Oct. 24 message in which I inserted replies to David's comments, I noted that we agreed to defer voting on the glossary definition of Taxon---but
I unfortunately forgot to remove this item from the list of changes that we are voting on right now. My apologies for the confusion!<br>
<br>
The attached document is identical to the one I sent you on Friday except that I have deleted the glossary definition of Taxon as one that we are voting on at this time. I am not trying to suppress discussion of this item. We will return to this and related
changes in the code (and also revision of Art. 21), but after many months of discussion, I think it is best that we vote on the several changes that no one has expressed disagreement about.
<br>
<br>
I suggested on Friday that we call a vote on this set of changes today if there were no comments by Sunday and if no one objected to this schedule. No one has objected to the schedule, and the only comments are on the glossary definition of Taxon, so let's
please vote on the other changes (attached). Please send your vote to this listserv by this Friday (Nov. 2). [If someone feels this is insufficient time in which to vote, please say so, but we have been discussing the CBM proposal for months.]<br>

argue that it is useful to distinguish terminologically between groups composed of an ancestor and all of its descendants that conform (more or less) to a nested hierarchical pattern (species, uniparental organisms) and those that do not (biparental organisms).<br>
