License

Plugin is free for everyone! Since it’s released under the GPL, you can use it free of charge on your personal or commercial blog.
Windows Client is also free of charge since is in ALFA or BETA state. After final release will be one-time small cost without any monthly costs like competitions have. People who help me test and brings some nice ideas for sure will obtain full license for free.
