Advertising Forum

Why do you make Advertising into a Forum Instead of a Catagory?

It makes it much easier to get to if it was a catagory, people might get lost and not be able to find it =).

But what i think is IF they put advertisement in seperate category the forum will be too long. what they can do is MAke their announcements and feed backs section into a forum and leave the Advertisements as a Seperate Category ..Right northwind?
