That's right. We can give each other feedback. Positive, neutral, or negative. Use this when trading or give someone kudos for helping you identify a chip, fix your computer, or doing something else that's worthy of kudos. Or, if you felt another member treated you badly or violated the code of ethics, you can use it for that as well.
To use it, find a post of a member you want to give feedback to, click the number to the right of "Trade Count" below their name, and fill in the form.
Remember that other members will see this count and your feedback (and your name/ID), so use discretion when giving neutral and negative feedback. Being sober during the process helps as well. :)
