How do you get the top Contributor logo thing in your answers

I mean what level do you have to get to?

You can get it at any level, I think. You may need a 2 level, however, you have to
have a significant number of answers in ONE SUBJECT AREA and a reasonable
best answer percent, I think at least 10%

Its not really a level.. .you just have to answer a bunch of questions in the same category consistently (maybe for a week?) I think they check once a week and if you stop answering you lose your logo

I guess you have to be very active. Check out this link

Not a level, but you have to contribute hundreds of thousands of answers!
