Let's say you want to test LO2 with a different nodeStorage server. 

Suppose the server is at http://storage.myserver.com:1999/.

In Little Outliner, open the JavaScript console, and enter the following:

switchServer ("http://storage.myserver.com:1999/")

The page should reload and you should get a screen saying to sign on to Twitter. 

You should be prompted to create a new outline, if this is the first time you've used LO2 with this server. 

From there, you can use LO2 as you would on the default server.

If you want to switch back, enter this in the JavaScript console:

switchServer ()

Same process happens but you're transferred back to the default server.
