I was reviewing questions seeking help in resolving issues the various posters of the respective questions had with different aspects of Blender. Now, while the particular questions I was paying most attention to dealt with modeling issues, I noticed questions about other areas of Blender, too: animation, texturing, rendering, &c., and it occurred to me that what many of the questioners needed more than they needed an answer, was a guide to how to find the answers to their questions themselves. Of the books I have read, the tutorials I have reviewed, and discussions I have followed, not once have I found a resource which, given a particular type of problem, say some tool not working as expected, presents a list of suggested steps in how to help a user find the answer.
What do you think about the idea of a series of pages, titled, "When you have a problem with > <, here are some things to look for to solve the problem."? As a concrete example, a recent question asked about an interrupted loop cut, but I suspect that the person who asked the question didn't think (or didn't know) to switch to vertex select mode, in which the problem would have been quickly identified. I remember another question about textures not appearing which the answer was simply that the one asking the question had the display mode set to solid. I expect that a current question about why a render is all gray will turn out to be similarly trivial to solve.
I think a good format is to write a "question" introducing the check lists, and have a series of answers, one for each area of blender, where things to look for are posted, somewhat on the format of the "Resources for Blender" question.
