PLEASE add Send & Track back into the documentcloud.adobe.com website
Send & Track on documentcloud.adobe.com allowed sharing an item BEFORE uploading it. This was extremely useful for 2 reasons: Multiple files share all at once; Didn't have to wait for an upload to finish before sharing. The new Upload File function requires waiting for a giant upload to finish before you can share it. This is no better than DropBox which is much easier to use than Send File.
