When I clicked the new profile information this week (today 17.4.2015) I seem to have chosen to always show my Activity page as first choice.
That is, when I enter this page: https://math.stackexchange.com/users/8530/mats-granvik
I am always shown this page:
https://math.stackexchange.com/users/8530/mats-granvik?tab=topactivity
What I would like to see is this page: https://math.stackexchange.com/users/8530/mats-granvik?tab=profile
I have clicked other users and their pages show the Profile page and not the Activity as first page.
Where can I change this?
