There are bounties intended for newbie. Just scan through all of the bounties on the link below. I never thought there are some so what I did was just to scan all bounty projects on the Altcoins Bounty section (https://bitcointalk.org/index.php?board=238.0) on that link. I was so happy to see that while we are a newbie we still are being given a chance. Just read their post and you will be guided what to do. Usually there are application forms where you will be signing in your bitcointalk account. Then a spreadsheet link is also there to see if you are accepted. Try to send message to other for guidance maybe they can help also especially the high ranking forum members. I'm sure they are willing to help given that they are not so busy.
