I agree with Rich Richie. What purpose does removing this link serve other than make becoming an editor that little bit less accessible? It wouldn't even have to impact the design or anything, just make the title of the box the link to the Special:WikiActivity and you're golden.

Edit: The problem is even worse on mobile devices when in desktop mode because the header is at the top and the box at the bottom, meaning that on any reasonably sized page, they can't share the screen.
