The full announcement is at http://blog.python.org/2013/03/introducing-electronic-contributor.html, but a summary follows. We've now moved to an electronic Contributor License Agreement form at http://www.python.org/psf/contrib/contrib-form/ which will hopefully ease the signing and sending of forms for our potential contributors. The form shows the required fields whether you're signing as an individual or a representative of an organization, and removes the need to print, scan, fax, etc. When a new contributor fills in the form, they are emailed a copy of the form and asked to confirm the email address that they used (and received that copy at). Upon confirming, the signed form is sent to the PSF Administrator and filed away. The signature can either be generated from your typed name, or you can draw or upload your actual written signature if you choose.
