Does replying and posting are the same to increase my activity? I just notice that when I am replying to a post, it increases my activity number. Can someone confirm this?
Just like engrshu said 'reply' is also counted in your activity, but keep in mind that you can only earn 14 activity every 2 weeks. So even if you reply to 50 topics, your activity will only increase by 14 after 2 weeks.
