As everyone said,since you are newbie,you should mainly focus on social media part of the campaign so facebook,twitter,articles,videos etc.But if you are ready to spend approximately 12-13 USD you can upgrade your account to Copper Member and therefore wear member rank signature,as there are campaigns that accept those too.I think its worth to invest a bit into copper account,it will make your experience smoother here,and you might even profit extra by joining signature campaigns that accept those members.
