The 'donation' page for CFAR redirects to singularity.org after completing a donation.
ETA:
Also, the donation details (in both the confirmation e-mail from Paypal and the thank you from SIAI) all reference SIAI and not CFAR.

The new Center for Applied Rationality website has launched! We'll be adding content as time goes by. Let us know if you find broken links, etc.
