Imagine a website shoes.Q-A.com
The scope of this sight would be questions about shoes, but no boots or sandals, and no questions about where to buy.
Imagine the scopes are clearly defined in Help -> Help Center -> What topics can I ask here? Thats three clicks away.
Renaming of the site is not an option, but many of shoe's users have suggested it, complaining that the name of the site does not make the scope clear.
Neither can the scope of the questions asked change. The name of the site will always be shoes, and the scope will never include boots nor sandals.
What would be a good way to convey shoe's scope to users before they unintentionally ask a question that is out of scope?
I was thinking about simply making the most commonly made mistakes when asking questions more prominent and immediately available in the side bar under a caption such as "Is my question off-topic?" and this could list perhaps the top 5 to 10 misconceptions about shoes.Q-A.com.
