Link to profile in "badge earned" banner should go to activity page.
When I receive a new badge, the banner that appears congratulating me has a link to my profile ("Congratulations, you have received a badge '______'. Check out your profile.").
I notice that the profile link goes to my profile overview page (http://askbot.org/en/users/625/todofixthis/), but it would probably make more sense to link to my activity page (http://askbot.org/en/users/625/todofixthis/?sort=recent) so that I can actually see the badge that I just earned with the link to the post that triggered it.
This one will be fixed in 0.7.42 as it is less critical.
