There have been several times when I have been on Meta or the RMT, and I click on a user to see his/her score/questions/answers. But I'm usually looking for their PokeBase score. And thus, we come to my suggestion. Perhaps we (that is, you) could add a couple buttons at the top of someone's profile so you can easily switch between the Meta, PokeBase, and RMT profiles.
That, or when we're on a person's profile and switch to a new section we're still on that profile.
Just a couple thoughts.
