I use to have 1 now i have 2. lots of people have 5 or more. why are some bars a dark green and some a lighter green?
Reputation. Post quality posts and people will give you more. If you go to your "my account" in the top right, and scroll down, you can see all the rep you got
but see thats what im also wondering. both of you have the first half of your bars darker then the other half. whats up with that?
The first 5 dark blocks you get per 100 rep points. After the 5th dark green one, the light green ones you get for every 200 points.
Your light bars will come naturally if you continue to post and NOT ask for rep. asking for rep is frowned upon.
