I dont see how to award medals. I can create them but do not set criteria for their use or see how i can award a medal?

Go to Admin -> Users & Roles -> Medals -> and Click on Edit on The Right, on the medal you want to assign. Then you see on the Bottom to Areas

- "Medal Group Holders" - Assigns to a specific group

- "Individual Medal Holders" - Select a single user

Is there any way to award a medal to a specific post? I created a forum once and that was a feature that I included and it was very popular. If YAF doesn't have that I may have to do another modification.

Did you mean for a specific post Count or specific message in a topic. Ether way you only can assign the Medals Manually
