That is due to the change in rules as to reduce spam and other inconveniencing issues arising from new users and this new rule affected all Jr. Members without at least 1 merit.
So, if you want to advance to Jr. Get at least 1 merit. This way, new users will work hard rather than spam around
Yeah, this is true. There are so many spams and other inconveniencing issues in the forum before, so that's why the rule is changing. Just increase the quality of your post then you will get merit and go to Jr Member again.
