Setup Dropbox
Select the "Dropbox" option from the main wizard screen and you will be presented with the webdav configuration screen
After entering your login details click "Login" and press the right arrow button to be presented with a list of directories in your Dropbox account.
Click on subdirectories to enter them. Once you have located the folder that contains the index.org file place a checkmark next to that directory and press "Done". Note: we have at least one report of checkboxes not showing up in landscape mode; try portrait instead.
LAST NOTE: If you are a Windows user, you will need to have md5sum.exe or sha1sum.exe in your system path before org-mobile-push will succeed.
