Is there any way for newbies to build reputation besides spending months to become a regular? Maybe some kind of a guarantee given by an already reputable user?
Go to the games and rounds board; create a thread to give out $100 or $50 weekly to users by raffle. When anyone wins, send the money to them. Try it for some weeks, you will start getting positive review. I have actually seen someone did this in the forum. I'm sorry I had to be honest.
