Yes.  GeekHack now has stars associated with various member groups and types.  For the moment, we have only rolled out a few types as a trial.  More will follow.
The short version is that 
PURPLE stars are staff or others here to help.  
GREEN stars are for vendors and other members where money is involved.  
WHITE will be for non-profit/no-money sellers and service providers.
Staff     
 Administrator     
 based mod     
 Senior Moderators     
 Global Moderators     
 Marketplace Moderator
 or 
 Vendors of various sorts
 Non-ProfitWe will add more stars over time.  (We have a dozen ready to go.)  Some will be automatic; others will be based on a member's role on GeekHack.  And a few will be for community awards.
Anyhow, we think they are a good thing.  A small minority of the 
20,000+ 59,000+ GeekHack members will get a star.  A tiny fraction might get more than one.  Prize one if you get one.  Lobbying won't get you one, but helping the community flourish 
will help.
More information will be provided as the rollout proceeds.
TL;DR Stars are here. You want one. Be a good geekhacker and you might get one! - Ron | samwisekoi
