Why my rank is changed from Jr Member to Newbie. I didn't post from month and a half and my rank is changed. Should I do rank increasing by posting 2 posts per week to get again Jr Member ?? Or there is any another way to get back the rank?
System has changed already as you need merits to rank up. Check this page
https://bitcointalk.org/index.php?topic=2818350.02 posts per week ain't not working anymore, you will have to gain 1 merit to be a JR and then goes up to the Legendary. The better you posts in the forum that will lead to helping users, the higher chance you get merits.
