http://www.sheridanprinting.com/acm/sigweb-ht/sigweb-ht.cfm?id=ht105, and


on which I could upload my camera ready papers, specify the authors, keywords, etc. No password or other kind of authorization had to be entered. Now, guess what. I played around with the URL and tried, for instance, to open the following URLs in my browser.
