The quickest fix might be to just have a "sticky" tab next to Main and Discussion on the top.

Along with what the grandparent mentioned, this would also include: That month's Open Thread, and potential monthly book/media recommendations, Monthly quote thread, and other of the uber-useful non-Sequence posts.

Note: "Quickest" doesn't mean best solution. It just means something I think could be feasible for someone to actually do.
