Imagine the scenario, a company has a pricing error on their website, the chances are it won't be there long so you want to get it up onto the site quickly. You have two choices, do you run the risk that the admin is online and post it as an actual offer, or do you post it onto the forum? Not as many people will see it, but at least it'll be instant, right..?
Well, why not have the best of both worlds? If users had the ability to view any pending deals (maybe listed in a special forum?) that'd mean it'd be instantly accesible by the forum users, as well as being instantly accessible on the front page as soon as the admin comes online.
I'm bloody useless at explaining things, but hopefully someone will get the jist of what I'm try to say and write it a little clearer ;x
