FIRST CALL FOR VOTES (of 2)
unmoderated group sci.techniques.xtallography.rietveld
Newsgroups line:
sci.techniques.xtallography.rietveld Rietveld science and technology.
Votes must be received by 23:59:59 UTC, 5 Jan 1996.
This vote is being conducted by a neutral third party. Questions
about the proposed group should be directed to the proponent.
Proponent: Lachlan Cranswick <Lachlan.Cranswick@minerals.csiro.au>

RATIONALE: sci.techniques.xtallography.rietveld
The over 300 participants of the Rietveld mailing list have
agreed with attempting to convert the existing mailing list
to a full Usenet newsgroup. This is to enable easier discussion of
scientific issues relating to the Rietveld based applications
to a full Usenet newsgroup. This is to enable easier discussion of
scientific issues relating to the Rietveld based applications
via newsreading software and create an "open" Rietveld resource
on the internet/Usenet. This would also help negate concerns that
are inhibitting discussions on the basis that mail boxes are
already too cluttered.
If created, the old mailing list will still be mirrored to
the newsgroup so that subscribers without newsgroup access
can continue participating. While the method was originally
created by Hugo Rietveld for the refinement of crystal structures,
it has greatly expanded beyond these borders to include
such fields as quantitative phase analysis, crystallite
size and strain analysis.
CHARTER: sci.techniques.xtallography.rietveld
The newsgroup sci.techniques.xtallography.rietveld will be
an open discussion forum for the international Rietveld
research community on the internet/Usenet.
Topics for Discussion
---------------------
The main topics for discussion are (but not limited to) :-
Applications for X-ray and Neutron Powder Diffraction
User problems and suggested fixes.
New user pitfalls :-
(e.g., why does my Rietveld software, while refining
a hexagonal structure, give beta not equal to 120 degrees?)
Sample preparation techniques.
Data collection techniques and optimization.
Vendor/author announcements of Rietveld software
(commercial and public domain).
Reviews/announcements of Rietveld books, articles and software.
Comparison of rietveld software
Installation of Rietveld software.
Rietveld Goodness of Fit Plots and other Graphical Output.
Discussion of new code, functions, algorithms, etc.
Data formats.
Software requirements
Available Software
Reported bugs/glitches/kludges/"features" of various software and
their possible work-arounds or solutions.
Discussion/comparison of complementary techniques :-
e.g., direct methods, maximum entropy.
Any other topics users consider relevant (suggestions welcome).
END CHARTER.
HOW TO VOTE:
Send E-MAIL (posts to a newsgroup are not votes) to:
voting@ntrs.com
Replying to this article should work, but check the address before you mail
your vote. Your mail message must contain one and only one of the following
vote statements for each group:
I vote YES on sci.techniques.xtallography.rietveld
I vote NO on sci.techniques.xtallography.rietveld
Names are required for this vote. The counting software will extract your name
from the mail message if your mailer is properly configured; if your mail
software does not indicate your name, you must include the following statement:
Voter name: Your name here
You can also vote ABSTAIN or CANCEL. These votes are not counted in the
results, and CANCEL removes your name from the vote listing in the result.
Vote counting is automated. Failure to follow these directions may mean that
your vote does not get counted. If you do not receive an acknowledgment of
your vote within three days contact the votetaker about the problem. IT'S YOUR
RESPONSIBILITY TO MAKE SURE YOUR VOTE IS REGISTERED CORRECTLY.
If you wish to change your vote, simply vote again from the same account;
duplicate votes are resolved in favor of the most recent vote.
THIS IS NOT A SECRET VOTE. Names, addresses, and votes will be published in
a RESULTS article in the same newsgroups in which this CFV appears.
The purpose of a Usenet vote is to determine if there is sufficient interest in
the Usenet community to create a new newsgroup. Soliciting votes from
disinterested parties defeats this purpose. Please do not distribute this CFV;
direct people to the CFV in news.announce.newgroups. Distributing pre-marked
or edited copies of this CFV is prohibited, and votes from such sources will be
removed from the final vote total.
Standard Guidelines for voting apply. One person, one vote. Votes must be
mailed directly from the voter to the votetaker. Anonymous, forwarded or proxy
votes are not valid. Votes mailed by WWW servers are considered to be
anonymous votes.
DISTRIBUTION:
In addition to the groups named in the Newsgroups: header, the first CFV
and the eventual RESULT posts will be mailed to the mailing lists:
Mailing list name: Rietveld Users Mailing List
Submission address: rietveld@xtal.cmc.uab.edu
Request address: rietveld-Request@xtal.cmc.uab.edu
