This is getting more and more confusing by the minute:
When setting the parameters for Achievements, what's the difference between 'Posts' and Points for Posts'?
Clearly, something is adrift because I used the value 2000 for 'Posts' (x2 points each on my board) and a member with 800 posts got the achievement (should be 1000+ posts). I then changed the achievement to 2000 'Points for Posts' and again the same member was credited with a 1000 post achievement.
Finally - is there a way to exclude Admins from showing Achievement icons? I've excluded the Admin Group from calculations; the bars have gone but the icons still show.
