I was confronted with a question of which I scarcely have no clue of what to say as an answer to the question.
Though I have seen some newbie doing signature bounties and recently saw two which offers newbie the opportunity to participate.
Now to my question, can newbies wear avatar? If yes, how?
You cannot wear avatar if you are a newbie. You need to be a Full Member rank and above to have an option to wear it. If You saw a campaign that requires avatar for newbie, it means he doesn't know what he is doing.
