Hi, I changed my email address recently and have discovered that my kuler themes and favorites have all vanished. I know other people have had this issue and it seems to be infuriatingly difficult to contact someone at adobe about this so hopefully one of the kuler team will see this and be able to help out.
Report this to kuler team via 'Report a concern' link
I've been meaning to get around to this since... well, January. Thanks for this, I've sent them a message so hopefully they'll restore everything.
