If you’re learning Inform 7 and need help, there are a number of resources available to you.
The Interactive Fiction Community Forum is a moderated place to discuss IF; it features a dedicated board for Inform development. People here are great at responding to questions with helpful answers, and you can search through the archives to see if a previous conversation helps out, too.
If you like to chat with people in real time, you can usually find several Inform experts hanging out on ifMUD.
If you can’t get something to work the way the book says it should, check the Errata page first to see if there’s an error in the book. If that doesn’t help, or if there’s anything in the book you find confusing or misleading, I’d love to hear about it so I can improve any future editions. Contact me via e-mail and I’ll get back to you promptly.
