-- Attention --
nzbs.org seems to no longer accept new registrations, so if you don't have an account already you won't be able to (fully) use this application.
v0.71: Bugfix (Downloading to Local NZB didn't do anything)
You need a free nzbs.org account.
And either a HellaNZB server or an FTP server to upload the .nzb files to.
