Thanks for your feedback.
It's not only you,
Seems aks platform doesn't want to rank anyone with text 'ingo' in their user name, check @ http://www402.abbext.com/ExpertSearch.aspx?keywords=ingo. Anyway jokes a part.
We will investigate this and display missing rank status. Sorry for missing profile data. Keep browsing and participating on AKS.
Thanks for your contribution on AKS and for your understanding.
