Knowledge base
The site looks great. I have a group of 75 cases (growing daily) titled "must see cases, R2" in our local version of MyPacs. We could use some of these to grow the file. I think that this is an excellent approach.
As far as the "knowledge core" do you recommend using links or uploading PDFs. I am not sure if this is a copyright violation or not. We do it in our internal version of MyPacs, but never in public. Otherwise the links and let the individual download the article under his/her university's license. Which do you feel is best?
I have a sample article in mind from the rheumatology literature: from Arthritis and Rheumatism

I am giving a talk on arthritis imaging for the ACR (rheumatology version) in SF later this month and have a very recent bibliography on arthritis imaging to "prime the pump" if you think helpful.

Core papers
By all means, add as many cases as you like to the Must See Cases (SABR Gallery), and add as many seminal articles as you like to the Core Knowledge Base (on the SABR Wiki).
