The "Newbie of the Month" challenge is meant to show new member on GuruShots how things work.
These members can join this challenge and other open challenges.
Due to that, they can move to higher status level in less than 24 hours.
For example, a new member who has just joined GuruShots (and the 'Newbie' challenge) can be in +25 challenges within an hour.
Depending on the closing challenges, it's possible to reach 'Rookie' or 'Advanced' status within 24 hours.
All you need is to you reach 'Premier' level in all of them (600 points each, 10 Premier level achievement and 5 Successful Swaps).
