I installed Pogoplug a few months ago, but haven't done much with it, and I've mislaid the manual.  Is there a PDF somewhere that shows basic information such as the connections?  I'm looking at my.pogoplug.com/help, but it only seems to cover software issues.

My most immediate question - is there any difference between the front USB connection and the 3 on the back?  Is the one on the front just there for convenience?

Thanks!
