I just have a small doubt. When we promote to junior member and join some bounty, there is a requirement of minimum posts. What does that mean? Do we need to post about their ICO or we can post anything helpful?
Every signature campaigns has its own specific rule in posting and you should follow it to be able to get the reward. Some rules may need you to post on their thread everyday, or to post helpful and on-topic replies to a specific sub-forum.
