The Help & Search button should be right there after you click Navigate, without requiring any additional scrolling. It should just be click, click no matter where you are on the site.
Oh wait, perhaps you mean click, click, scroll... you do have to scroll down a bit on the Help & Search page to get to the search bar.

I kinda feel like I want to explain something about this beta test. Some folks are treating it as if everything that's they're seeing on screen right now, on the third day of the beta test, is the way it's going to be permanently, forever. But part of the purpose of testing is for me to figure out what works and what doesn't work for people.
I cannot possibly account for how every single DU member uses DU, and how DU is going to appear on their devices -- it's taken three-plus years to get to this point because I've done my best to try.
So far I'm getting the impression that most people who are using DU4 are finding it to be an upgrade. But I was well aware going into this test that some would have specific issues with it. What I'm trying to do now is see if there are ways to resolve those issues -- and if there aren't, at least do my best to explain that there may be alternatives to the "workflow" you're used to, that you just haven't found yet because some of this is new.
I noticed upthread that usonian was lamenting the current trend of sites becoming user-unfriendly because of developers "rushing stuff out the door" -- I really hope that people don't think that's what's going on with DU4. This redesign has been a labor of love for me over the last three years and I want everyone to be happy with it. If there are things I can do to resolve your specific issues, I will do my best.
