They are all listed on the front page of www.amsat.org.
I use the STATUS page to help my students track and find satellites but the arrangement of that page has always been frustrating to me for two items that I think could be fixed to improve the user friendlyness.
1) Put them in launch/oscar-number order. The present order seems random.
2) Put both their NAME and oscar number in the table. With so many cubesats, their Name is more meaningful than their oscar number as to remembering function. List both, let the user use what he remembers.
3) Include all satellites that are in the amateur band, whether they are OSCARS or not.
If we want to reach out to students and others about the excitement of space, the AMSAT web page is a great resource. But the few tweaks above would make it much more user friendly.
