Luscinia has been produced as a project for my own research. I hope it is helpful to others too. I continue to have a career as a research scientist. Therefore, I am sorry, but I have a limited ability to respond to queries about Luscinia. I cannot guarantee to fix a bug, however important it is.
Please do not hesitate to contact me about Luscinia, though. I welcome feedback, positive or negative: use the online bug reporting/feature requests at sourceforge. For other questions, please see the forums.
