Joined for a year and half way there.
I tend to refrain from posting too much through, usually when I can help people out rather than in news items.
I think there should be a rating system for users, other users can rate you on how helpful you've been to other users and that contributes to your profile on way or another
just an idea.
Something to reward those who try to help others rather than post 100s of 6 word responses for news items every day and to increase incentive for posting helpful responses.
