Well, since more than 300 users have joined the service, Its no longer free. At least he's allowing the people that already have an account to still be able to use it for free :).
I would like to have support for sending URLs for it to download via the command-line (where it will show the main window and download the specified url, then close the main window when done downloading and have it stay running in the system tray) and support for Rapidshare, etc. added to it.
