Twitter for clay mineralogists-Hashtags

A common tool on twitter is a hashtag (text with a "#" symbol before it; i.e. #Euroclay2015; it is also used on Facebook now). The hashtag was invented as a label for groups and topics in IRC (internet relay client) chat. Adding the '#' before text made that text easy to find in a search query. Twitter made the hashtag a mainstream tool.
   So what does it do for you? Twitter users can use a hashtag to filter their messages. When a Twitter user clicks on a hashtag, it redirects to a page with the stream of tweets containing that hashtag. You can also find hashtags that sound interesting using search. This is how you find things on Twitter by topic. 
   If you tweet about a topic often, you should probably include a general hashtag. We currently tweet often with #claymineralogy, #Euroclay2015 and #yearofmud as these are terms that our audience is using to find information important to them. If you hashtag, followers can explore other tweets related to the topic. This is one way we hope to build our online presence and communication between members of The Clay Minerals Society.
  We realize our tweets will most likely not be a viral topic, trending worldwide. We do hope that the use of hashtags on Twitter will allow us as a community to communicate better and increase our groups visibility in the growing world of social media. So don't forget to tweet about #Euroclay2015! Tag us @ClayMinSociety so that we can retweet them via our account and let more people know about the events happening at the upcoming annual conference.
 We look forward to hearing from you (@ClayMinSociety).

President's Corner

In this issue of E-news, I comment some on my year as President of the CMS.  I am happy to report that the CMS Presidency did not have any serious crises. No rascals. Things went smoothly. I thank Michael Velbel for leaving the CMS in good shape. The CMS benefits from a dedicated membership. Some of these dedicated members pitch in and do some tremendous work and donate much time.  As for highlights, our Source Clay Repository has two new clays to replace our Wyoming Montmorillonite and Georgia Kaolin source clays.  The Impact Factor for Clays and Clay Minerals is improving. This improvement speaks to both quality of submissions and timeliness of journal operations.  Acting Editor-in-Chief Michael Velbel, the Associate Editors, and the Managing Editor, Kevin Murphy, are congratulated on a job well done.  One goal of pushing out knowledge was met by this E-newsletter. Our student grants awards are well subscribed. Our support for students is one of the best things that we do.  The Awards Committee tell me that they have some good choices (I do not know these choices.) to make for the 2016 awards (Bailey and Jackson).  
    The upcoming Annual Council Meeting, to be held in conjunction with the Euroclay meeting, will mark some changes in our leadership (pending Council vote).  Reed Glasmann will be stepping down after nine years of distinguished service as our Treasurer. The last nine years were challenging years to the CMS budget and endowment.  Through it, Reed was a composed and steadfast steward of our fiscal resources. Well done, Reed.   Paul Schroeder is our Treasurer-elect. He is ready to go.  Prakash Malla will be our new President following our Annual Meeting. Likewise Prakash is up to speed on CMS operations.
    Euroclay looks as though it will be an excellent meeting. Steve Hillier and all have outdone themselves. They have set a standard that will be hard to meet.
   For me, it has been a privilege to serve as President for the past year. I stand ready to assist Prakash when needed.  I thank everyone for their support and good wishes throughout the past year.
Crawford Elliott, President
William D. Johns
The Clay Minerals Society Office received notification of the death of Professor William D. Johns (University of Missouri – Columbia) in March, 2015.   Bill Johns was certainly a very well-liked and highly respected member of the CMS.  His work in clays centered on the petrology and clay mineral transformations in petroleum source rocks.  He and his students studied the Tertiary section of the Gulf Coast province as well as other potentially important regions for oil and gas exploration in Europe (Vienna Basin of Austria, and the Pannonian basins of Hungary, Slovakia, and the Czech Republic).  Bill served the CMS with distinction. He received A Citation for Special Recognition in 2003 acknowledging his 30 years of service in running the CMS Source Clays Repository. He delivered the Brindley Lecture in 1989. He was President of the CMS in 1982-1983. He taught at Washington University and at the University of Missouri-Columbia (  Memorial Contribution may be made to the William Johns Geology Student Scholarship Fund, c/o University of Missouri-Columbia, Department of Geological Sciences, Room 101, Columbia, MO 65201-9984.
