Not a problem. All of us are too busy and we have to ignore some messages.
In VoteFair _negotiation_ ranking, _participants_ rank _proposals_ .
In the other kinds of VoteFair ranking, which are named using the
words "popularity", "representation", "party", and
"partial-proportional", _voters_ rank _candidates_ .

Hopefully the following description of VoteFair _negotiation_ ranking
answers your questions. If not, feel free to ask more questions.
You can post the description on your wiki.
---- description below ----
The purpose of VoteFair negotiation ranking is to calculate a
negotiation outcome that comes close to what would arise if a consensus
process -- with continuous feedback -- were used. This means that
significant-sized minorities get a significant level of influence. This
approach contrasts with methods that allow the majority to have full
control. And it defeats the blocking tactics that work in full
Using the VoteFair negotiation software at www.NegotiationTool.com ,
each participant ranks all the proposals. There are three general
categories: "liked", "neutral", and "disliked". Within the liked and
disliked categories, each participant ranks the proposals, putting their
favorite proposals at the top, and their most-disliked proposals at the
When new proposals are added, they appear in the "neutral" category, and
the most recent proposal appears at the top of that category. A
participant can then move these new proposals into their "liked" and
"disliked" categories, and rank them above the proposals they like less
and below the proposals they like more.
In addition to the need to rank proposals, the software needs to know
which of the popular proposals are incompatible with which other popular
proposals. To do so, either an administrator (such as an arbitration
expert) can specify incompatibilities, or the participants can vote on
incompatibilities (in which case a threshold is involved).
Based on the rankings and the incompatibilities -- and nothing else --
the algorithm calculates which proposals can be combined into a document
or agreement or law, such that the result is likely to be approved by
most of the participants, or at least approved by a majority of
If the early results include proposals that are obviously incompatible
with each other, then the incompatibility information needs to be
corrected (either by the administrator or by participant voting). There
is no need to exhaustively indicate all possible inconsistencies because
lots of proposals will not be popular enough to get into the group of
The www.NegotiationTool.com website currently does not support
delegation, but the internal software allows for the possibility of
specifying more than one vote for participants who are acting on behalf
of other, non-voting participants.
What might be called the "liquid" part of VoteFair negotiation ranking
is that participants can add proposals at any time. If there are lots
of participants, the added proposals can be "vetted" (approved for
addition) by a neutral administrator, and the administrator can remove
proposals that obviously will not be accepted in the calculated results.
The goal here is to keep the number of proposals reasonable.
The encouraged strategy is to split unpopular proposals into several
separate new proposals. This allows the participants to highly rank the
parts they like, and lowly rank the parts they dislike. The recommended
result is designed to produce both gains and concessions for almost all
The algorithm does not attempt to identify when the negotiation process
is done. If the participants have a genuine desire to reach a mutually
satisfactory agreement, then the results will slowly converge on an
optimum set of approved proposals. An external yes-or-no vote with a
majority of yes votes determines when the negotiation is done.
To see what a participant ranking looks like, and what an overall
calculated result looks like, follow these links to an example in which
an employer and an employee work out a terms-of-employment contract.
The www.NegotiationTool.com website also includes an example in which
parliament members choose cabinet members, which is a very challenging
negotiation process that the software easily handles.
