Unfortunately mate, there are so little selections of campaigns that accept newbies, so it would be a better option to rank up your membership first to Jr. Member instead of trying to find a campaign that accepts newbies, which is very rare. Also, you have to consider that the stake you get for Jr. Member is not that much, what more for a Newbie account, so it's better to rank up first, at least by then, you would have more options to join projects and gain bigger stakes as well.
