How do u create a bio is there like a copy and paste then put ur info in and also how long does it take to become a scratcher

It can take anywhere from two weeks to a month to become a scratcher, it depends how much you are involved in the community. Follow a few people interact with and comment on projects, plus sharing at least two of your own and you will soon get the rank.
As for setting a bio, just click on the about me tab on you profile page and type.
