I see from a post by Liam Dilley that you have "Changed the Terms and Conditions for using the SFTP upload system. All of my development sites are on catalyst and I cannot do any updates to 7 July-September releases. Where is the secret "Sign Up" for the new Terms and Conditions of Service hidden?
As per usual this SHOULD have been much publicized BEFORE it was instituted I have 3 VERY unhappy clients who need to do site reviews and PageSpeed tests but I cannot upload three sets of optimized images for their July-September Quarter mobile sites.
