New Post: Can't graph single user's network

I posted this issue in the "Issue" folder, but since it has been canceled, I am re-posting the same thing here.
My problem is that I need to monitor edges between one single Twitter user and its mentioners/retweeters. But when I download the user's network NodeXL categorizes edges only as "tweets", even if there actually ARE retweets, mentions, etc.
So it gets impossible for me to analyze the interactions for a specific account.
Am I missing something?

thank you,

Lorenzo
