Lately the way solutions are displayed have been changed. Before, if you clicked Solutions on the start page, you would get a list of the past weeks. But now, you get a list of all of last weeks problems (and below the previous weeks, and so on). I don't think this new way is very good, since it's a lot harder to get an overview of the past weeks. If you want to find a specific problem, I think it's harder, you have to scroll quite a bit. And since the Algebra and Number Theory problems are below the Geometry and Combinatorics ones, you have to scroll a lot just to see those.
In my opinion, it's much better to click your way through than having to scroll through long lists. And especially if you want to find a problem from a few weeks ago (if you e.g. want to give it to a friend), it's very hard to find.
These are just my thoughts and opinions, I don't know if others agree with me.
