Would be nice, yet I don`t think that at least half of people would pay attention to it, but simply click "yes". You can come up with some kind of image, what this option would look like. To be something that no one could overlook before posting, make it well visible for people. Eventually two little boxes to mark either "yes" or "no". But that could be uncomfortable for people who post there sometimes asking for help not really related to the stuff included in GHUS. The other option could be like after clicking "new topic" there would be a window showing up with the same question, so you would have to click yes before you get ability to make the topic and write what you want. Clicking "no" would automatically redirect you to GHUS.
But well, I don`t want to post my own version of it

Although, I vote No on that one, I don`t think it`s so necessary.
