Its crazy - I see people with like 10 bars of green rep boxes and a lot are stuck at 1 or even red. How do they get so many? Its pretty hard to even get 1 positive rep.
Always concentrate on helping and interacting well... with members, and everything else will follow! Regards, RightMan
Find people that need your help, and help them. Underneath the slime and ooze, there's still a really good bunch of DP nerds (old and new) willing to help each other - purely because they can.
What does rep stand for? Reputation. How do you get rep? By participating in the community and helping out. If someone likes/dislikes your post they will feel compelled to leave rep. You should try it sometime. It feels better then drugs (well that's arguable) but best of all its free.
You should also remember to leave your user name with your rep comments, that way people know who left it and may leave some in return. Thanks Brian
