If you want to talk about NVGT or programming/game development in general and the topic you want to post is not specifically a question about how to code something, a fully completed game demonstration or a bug/suggestion about the engine, you can feel free to post that here.
For example, discussions about favorite code editors, coding styles, game ideas, funny coding errors or anything else remotely similar could be posted here.
Bugs and suggestions should be posted either in the engine feedback category or in the issue tracker on the engine's github page.
