Reputations

There are a couple ways. On the upper right corner of the text box you will see a little grey bar with a plus and minus sign. If you touch the plus on that post it will give that specific poster a few rep points. Also if you hit the minus symbol it will take away that posters rep points.

When you hit the plus or minus is totally up to you, but use it wisely.

Also, when you write a new post you as the original poster have the option of thanking someone who provided you some useful information. When you "thank" someone they receive more points than the plus/minus bar.

So basically you have no control on how you receive points, but you do on how you give them.

Looks like someone has given you some for asking the question.

Hope this helps.
