serey.io new account signup question???????????

 Hello serey.io Today I came to answer a question. I've invited some friends to serey community. They signed up here, they received a verification email in their email but they did not get a password. They have applied for the account Already have been over for four days. There is no mail from serey.io in their mail yet. Now my question is, how long will it take to get an account approval? please answer me in my comment box. thanks, serey.io
