Wonder what will the criteria for a rank change in this forum? I mean to move form Jr ->Member ->Full member etc. is it number of posts you contribute orhow long you've joined the forum?
if you want to ride your rank of jr-member, you should see its rule, your old level of list in the forum has no effect, the priority is merit and activity. if you often ngepost with quality in terms of useful for the readers then you will be given merit
