Dear Colleagues, This is a test message for the listserv. Please note that the listserv address is listserv@mail.songyuan.org (that is, with the subdomain mail.songyuan.org now specified). This change is because I have just moved the www.songyuan.org website from the UCI server (my home institution) to a commercial platform. There are some bugs related to the fact that the commercial server is case-sensitive in its file naming, so some links to files and graphics images have been broken. I have fixed those but have no idea what else doesn’t work, since I just moved it. If you happen to notice a bug, I’d be grateful to know. I can’t guarantee a quick response, but I’ll get to it. Thanks. Michael
