With Ripple, how can I move my wallet to/from Payward? When I created my ripple wallet, I selected local computer.  Now I want to be able to access my wallet from any computer.  How can I move my ripple wallet to the server?

Or suppose I want to remove my wallet from the Ripple server (why would I want to do this?), what is the correct approach?
I'm seeking for an authoritative answer for myself, but it seems the answer to the first question is:


  On account creation (and whenever you login) you can set the "Fetch
  wallet from" option to one of "Payward", "Payward and Local Browser"
  or "Local Browser".
