What's the purpose of you achieving a higher rank on this forum? Is it primarily to enable you to participate in campaign signatures? If that is the case, then chances are you are not going to rank up.

In order to rank up, you need merits that people would commend you on the threads that you post. If you mindlessly post about nothing but nonsense or spam in the forum, then I doubt you'll ever receive one. Remove that mindset of ranking up and instead, focus on creating useful threads that will benefit the community. The more you think about actual contribution, the more that your post quality will improve.
