Regarding providing system information in the profile I think it’s better to include it directly in the discussion when it’s relevant. Providing it in the profile can be good too but you easily forget to update the profile each time SketchUp updates (my profile said I had version 6 - 2014 installed) or when you get a new computer. If you frequently use SketchUp on more than one computer (e.g. at home and at work) the profile information does’t tell on which computer a specific problem occurred.
