There's an e-mail list available if you want to discuss the JW Lua plug-in and its programming language specifically, for example script programming questions, sharing scripts, feature requests, etc.
Sign up on the e-mail list at: http://jwmusic.nu/mailman/listinfo/jwlua_jwmusic.nu
When you have signed up, you'll get a confirmation e-mail that you need to reply to to activate the list for your e-mail address.
Sometimes, the mailing list has many mails on one single day, so you might want to set up your mail software to automatically sort the list mails in a separate folder, or you can subscribe to the digest version (set “Would you like to receive list mail batched in a daily digest?” to Yes when you sign up to the mailing list).
