Rolf, my response to your e-mail regarding the password bounced. Here is what I sent: Rolf, thanks for taking an interest in my post and questions, I really appreciate it! Anyway, I found that ftp site by stumbling across this post: http://www.nyxdata.com/nysedata/Home/DiscussionBoard/tabid/108/forumid/4/postid/3744/view/topic/Default.aspx Of course, that forum is for Openbook, but if you click on the link he posts in the second post on that forum thread: ftp://sampledata:[email protected]/custom There are several subdirectories, one of which is ArcaBookMulticast. It's never asked me for a password, I kind of assumed it must be some sort of generic 'anonymous' access.
