Before this update Bbs started a competition of Weekly Top Posts just to improve the quality of the Content. 

No Announcement about the winners 

But now after the last update they didn't announce any winners of the weekly top posts . May be they ended that competition

Purpose of that Competition

According to me the only purpose of that was to encourage members to improve their content quality 

Why they are not announcing Winners? 

May be now that competition is not needed because everyone is trying to post quality content because they know they will only become partner if they post good content and partner also know if their content quality is drop they might be removed from partners 

Its just my thinking, May be they announce the winners of two or three weeks together like once they did in past
