I never get approved by steemit.

After more than one week of registration, i never get an email anymore, to complete my registration form, such as to know my password for login.

But......tonight, i finally get it hahhaha. I dont know, how it works because some of my friend, their account has not been approved yet, even though they register the account a month before me.

Anyone know about how the approval works? Does the old email address is the key for the approval? Or any tips for those who wants to join our community, and getting the approval email soon after the registration?
