I have looked everywhere for this answer so I apologize if I didn't see it... why do some members have a silver or grey dot next to their username and some people have a blue dot next to their username?... it does not seem to be a reason with regard to number of post or date of membership. I have many posts over many years and I am a blue. I've seen people with silver or grey dots who have less posts and not been a member long. I'm just curious. Thanks.
