Thanks for the download. Never mind the invisibility. I'll see what's in the .zip! I couldn't see my own and some others for two days. Yesterday my own new ones were visible again but I couldn't make older ones visible.
A beta watcher told me they are changing the upload method at the moment. I've always noticed that things go wrong when they change major parts of the site.
It is evidently a geographical problem with some servers (not owned by DA).. I subscribe to email updates and this issue was supposedly fixed a day or two ago. I guess with a beast this huge and unwieldy, there will always be problems.. Thanks Dave, I have downloaded the file, and hope to be able to see your dev soon!
