kathleen414 we ended up with our well used Hot deals and tips as a sub heading
Have you tried setting Tips and Guides to Followed and setting the Hot Deals subtag to Not Followed? I think you would then only Tips and Guides in All Discussions, without seeing those with the Hot Deals subtag.
That does assume that the members who post deals add the subtag, which may not always be the case. But the eds will fix occasional mistakes and remind the member if they make a habit of it.
