You will gain 3 levels. Stupid thing about this all is: I can't get 20 stamps xD Max 19 stamps.. Am I screwed or am I screwed?
why only 19? even if u didn't take the stamp the first day, today is 29 and the month have 31 days, so counting from today , 29 30 31 + 17 days of august = 20 stamps and counting from yesterday are 21 stamps
