Today I have been looking for solution for making one of my "page" links linking to category of posts for one of my WordPress projects. I have found a few tips about putting "href" tags in description etc. But it have broken my layout.
Then I have found great WordPress plugin called "Page Links To" that would let you put any URL instead of your real page content (even external!). When you install it you get additional field in your Add New Page section where you can put your url. For me it works like a charm!
