How many posts are needed to no longer be a 'newbie'? I had read this forum for quite a while and had recently made some posts in other areas. Are you concerned that alienating people might not be good for the long term health of your community?
It would be unfortunate if good people who could make significant contributions will be put off by this policy change.
Have the 'newbies' been rustled up and put into a pen where non-newbies will rarely ever reply to them, and so they are unlikely to be part of conversations that would give them an authentic chance to become full members?
Are you trying to create an incentive for people to make a lot of posts that have little content?
I apologize if my questions are out of place in this part of the forum, I would have been part of the discussion about this policy change had I seen one.
