I want to get rid of some posts, old ones, that I don't really want to keep. I was thinking to create a category named 'old' and use it as a garbage can to trash everything I don't like from old posts.
Reason I don't simply delete them is the google traffic. Some of those pages receive 1-2 visits a day, so why not leave them? just as adsense traffic :)
Now I need a way to hide category 'old' from everywhere. I need a quick and dirty way to do this, preferably through functions.php - don't want to change every menu listing and add -old.
I also want to exclude posts inside this category from being displayed in 'related posts' section. But for this I guess I will have to take a look in the plugin itself...
