Loving these responses so far 
I guess the hardest part is defining what a top contributor is - and attributes that measure qualitative rather than quantitative data.
e.g. is a member who replies 50 times and 90% of their replies marked as solutions more of a top contributor who contributes 100 times but only 10% of replies marked as solutions?
At the moment, top contributors are fairly easy to identify, as they’re the ones we see the most around the community. But I’m guessing we need more concrete criteria that we can use to identify those close, or on a path towards.
