If you said you weren't an engineer, that's probably "what raised the flag." If you had said that you were an electronics engineer and not an a/c engineer, it likely would have been ok.

As TD2K said, the site is supposed to be for engineers asking professional questions. As I am a nuclear by degree, but mostly do mechanical work in practice, I can sympathise with beppi. I'm still an engineer; however, that doesn't mean I know everything a true mechanical engineer would. However, what the red flag does is ask the site administrators to review the post - it's a way to make sure the site is being used the way they envinsioned it would. A while ago, I wrote a FAQ about what are the site "rules" - this has been ok'd by the site administrators as well as having been run by some of the more senior members of the site. You can click on the link following my name to see what they are.
