IMO, this is bad advice for newcomer. Brand new/newbie should learn both forum and bitcoin first before join a campaign. Also bounty is only promising (as many people said) on 2017 only, and now most bounty is scam. Even if they get paid from the project, most of them only low value coin and not worth it. They work for 1-3 month, but only get paid around 5$.. It only wasting your time.
For OP you can follow @mk4 suggestion, he already give the best answer for you.
Bounty campaign is not only limited to this forum, they just made an announcement in the forum but they have a lot of task that even a newbie can participate. We have a lot of platforms for advertising, we have twitter, facebook, youtube, and ect... this is out of the forum, signature campaign are the campaign to be done in the forum, and of course a newbie would not be able to participate.
