If you made a calc and want to share it with the world, go to Sharing and Upload with "Visible to All" turned on.
This will save your calc to the cloud and tag it. It won't actually publish it and make it visible to all.
That currently requires an extra manual step.
For the time being, please post a note to this thread with your calc's (or tool's) name and I perform the manual step for you. (Send me a personal message if you want this done same day.)
Afterwards, your calc will appear under Downloadables and can be downloaded by all.
Thanks for sharing!
