People want to contact writers to arrange for public programs and presentations. 

Some of the authors have added their contact information to their Wiki page. 

Others have not.

If you are trying to contact one of these authors, you should either 

contact them through their publisher or check with their library in their local

community. A list of Wyoming libraries and contact information for them can be found at http://will.state.wy.us/libraries/index.html 

You might also be able to contact the author through their publisher. Publishers are listed as part of the information about the books the individual has written. Using the publishers name, you can search the internet for the publisher's contact information.
