If a saved settings file is available from a web server, you can send email to others with a link such as http://ucsc.gao-lab.pku.edu.cn/cgi-bin/hgSession?hgS_doLoadUrl=submit&hgS_loadUrlName=U where U is the URL of your settings file, e.g. http://www.mysite.edu/~me/mySession.txt . In this type of link, you can replace "hgSession" with "hgTracks" in order to proceed directly to the Genome Browser.
