After a bit of digging around on the internet, I found the name of someone who says that he is still CushyCMS’s Chief Technology Officer. I’ve contacted him via social to ask what’s going on with their product. I see little point in preparing new Blocs sites for CushyCMS, if that system has ultimately been killed off.
But you’re right @flashman we need better CMS options for Blocs. I have clients who use the in-browser editing feature of Adobe Muse/AdobeBC on a regular basis. I’m not interested in developing fire-and-forget sites. I need to created sites that clients can update themselves, and then sync their changes back into my original file.
