Documents are synced with Ubuntu One. TomBoy notes are the most important thing on my computer, and I synced according to instructions for 10.04 (Tomboy Web.) Yet after authentication, https://one.ubuntu.com/notes says there is nothing there. What gives?
Unfortunately, the web interface for U1-synced notes was removed on February 28, 2012. Note sync will still work, but you won't be able to access them online.
