Re: Participant Contributions via Anonymous Ftp
(WORKSHOP ON THE U.S. USE OF SURFACE WAVES IN MONITORING THE CTBT, 
March 19 and 20, 1998; Univ. of Colorado, Boulder)

	 Following the lead of the DOE/USGS Location Workshop that 
Bob Engdahl organized in Golden in November of 1997,  we request 
that the participants of the workshop provide a summary of their 
contributions (text, a few figures called in the text) for inclusion 
on the workshop web page. The web page is at:

	http://abdu.colorado.edu/sw_workshop.html

	Participants may leave their contributions at CU's anonymous 
ftp site:

	ftp abdu.colorado.edu    (128.138.214.18)
	login name: anonymous
	password: your email address
	cd pub/user/ritzwoll/sw_workshop

	Each contribution should have text with a title that has 
your name on it and the number of your contribution (e.g., Anatoli 
Levshin's 2nd contribution would be levshin_2.txt). The text should 
refer to each figure by the name of the file (levshin_fig2_2.ps) and the 
files should be in one of the following formats: postscript, encapsulated 
postscript, gif, tif, or jpeg files. Compressed versions of these
formats would be best. Tar files are also fine.

	We will add links to your contributions on our web site
when the final report of the workshop is drafted, unless you explicitly 
instruct us not to do so.

	If you have questions or recommendations please do not 
hesitate to contact one of us either electronically or by phone at:
