I repeatedly find the same problems with questions, particularly (but not exclusively) from new users:
No model #s listed - just "a new dimmer" or "a new light fixture", etc. With model #s, which are always (well, perhaps except for some really junky stuff...) available for the new items (not as often for the old item being replaced), it is often very easy to find installation instructions online to answer the question. The OP may not understand the instructions (which is why they are asking a question, unless they simply ignored the instructions, which is a different problem) but there is usually someone more experienced who can decipher the instructions and solve the problem. But not without knowing the model #.
Country not clear. Recently there was one that sounded (based on 120V) like US, but then threw in some French references and that raised the "are you in Europe" question. It turns out this was French Canadian, but knowing the country is very important for electrical questions and often for plumbing or other types of questions too.
Pictures. A lot of new people don't know how to upload pictures. But pictures are often critical to figuring out problems (especially plumbing and electrical). The tour doesn't say anything about how to upload pictures.
Can we add two sections to the Tour?
- DIY-specific information for asking questions. Model #, country as I mentioned, and others may have some additional things to include.
- A brief summary of how to upload pictures, or at least a one-liner with a link. This would be useful for ALL StackExchange sites.
And finally, one part I can't easily check without making up another user (and I really don't like doing that). What, if any, notification is given to new users about the Tour? A number of people (including myself occasionally) will comment on a new post "Take the Tour". Ideally, in addition to (as I hope there already is but can't remember), new users being prompted to take the Tour after initial registration, I think it would make sense to prompt any not-yet-taken-the-tour-user to take the Tour when they start to ask a question. Just an extra click to either "take the Tour" or to "ask a question right away".
