Thanks. That's what I meant, but not at all what I even came close to saying.
The documentation does have a few gaps, and even if it didn't, it's a great place to find what you need when you know what you're looking for, but not always the best place to to get guidance on where to start. There's a project under development called the Twine cookbook, and its being worked on by contributors to Twine itself and some people from this Q&A. Unfortunately, it's still very much in its infancy, and I wouldn't consider it a great resource just yet. I'm just pointing it out because you aren't alone in feeling like Twine lacks some sort of official tutorial resource, and steps are being made.
The Twine wiki also exists, and it's not the best if I'm honest, but there are people actively working to improve it, and it has improved greatly over the last few months.
For right now, though, I think the best solution is exactly what you've been doing; search the old forum archive, take a look around the Q&A, and then just ask questions here if you can't figure it out. No one's forcing any of the answerers here to be here, we all choose to be a resource to this community to the extent of our abilities, and if you need to ask a million questions, that's fine (provided, of course, that you make a good-faith effort to find an answer on your own first). This isn't a perfect solution because it takes time to get an answer--time you could be using to write your story, but you shouldn't feel like not asking is somehow sparing the rest of us.
It's also worth pointing out that this Q&A itself will also become a more useful and more complete collection of advice and guidance as more questions are asked, so in a sense, you help too when you post here.
