I have spent so much time here without realising that you need to post as well. Assuming I have been active for 30 days without posting can I just post 30 times ? I doubt it will work
Activity is designed in a way that you need not post daily for it to rise. You can complete all 14 activity in a particular activity period by making the 14 posts in a day. You can even post more and these will be counted when you make at least one post in ext activity period.
