Yep, i've been using it for a long while.
Some of my personal favourite functions are the way you can uploade files from windows explorer, and the way you can copy and paste urls into the wizard (you can also have the wizard open automatically if you want when you click on a sendspace url but I found this irritating so disabled it).
I also really like it's ability to save and resume downloads or uploads, even if your computer crashes.
With our dreaming and singing, Ceaseless and sorrowless we! The glory about us clinging Of the glorious futures we see,
Our souls with high music ringing; O men! It must ever be
That we dwell in our dreaming and singing, A little apart from ye. (Arthur O'Shaughnessy 1873.)
