Another note to anyone building Juice 2. You must input the Blogger server name as well as your username and password in the preferences window before you can connect. The URL of the XML-RPC server is: http://plant.blogger.com/api/RPC2 . In addition, XCode will recognize the GSPreferences framework you've compiled if you first delete the old reference to it and then add it again using "Add Existing Frameworks". Also, remember to add it to the "copy files" build phase.
