As a Jr. Member who is currently at a disadvantage in the current system, I aggree that this can create positive things, but I think it's a little too unfair for the new members or Jr. Members. I mean just think about it. We have to seriously crawl our way to the top, and what if I make a legit, helpful, merittable post and no one noticed it? Isn't that a little too unfair? Many efforts can be wasted just because you couldn't appreciate or you fail no notice a good post. What are moderators are for?
There's dozens of 'review' threads which you can post any posts than you feel are under merited. Although, you can't do this every time you can for the most substantial posts.
EDIT: while the previous member of this forum has it easy, just meeting their quota per post, the new members have it rough, it's really hard to get accepted in signature campaigns right now. It's like they're discriminating new members.
Campaigns have always required you to be a certain rank. Very few of the campaigns (excluding altcoin campaigns) actually allowed members and below to join their campaigns. Anyway, if your sole purpose is to join a signature campaign your going to find it very difficult to rank up.
