wrong username in (private) newsfeed

Hi,
I'm quite new to bitbucket/mercurial, so please bear with me, if I mess up something with this ticket.

Problem:
My Newsfeed at http://bitbucket.org/nureineide/ambestengestern.de/ shows commits coming from a user named "benjamin", although the actual bitbucket username that made these commits/pushes was "nureineide" (that's myself).
To give a hint what might be causing this problem: My username on my local machine (were the commits/pushes came from) is "benjamin", and my "username" entry in my local .hgrc is "benjamin".

I hope this makes sense. If not, I'm happy to clarify further.

Thanks for bitbucket!

Cheers, Benjamin
