Generally speaking the more 'fun' areas of the forum don't increase a members post count, the more serious area's such as cocker discussion, health etc do.
The reason for this is that if all forum areas counted then the post counts would be extraordinarily high so therefore members who assist other members in the 'on topic' areas (ie about cockers) will gain a higher post count then members who post in 'off topic' areas.
