After harsh learning, configs, and multiple times of trial and error, I finally finished the setup. I also tested it out and it working as same as what a website would do. Reply those passwords.
Anyway, for those who already registered before, kindly register back to this website again. This because I deleted all the accounts created before to avoid bugs and more complex problem that will happen up next. Sorry for this inconvenience.
NOTES: By all means, right now I truly know what does the feel to be an admin. This phrase is quite familiar to all of us when registering a username using an email. Please check your spam/junks folders if the email didn’t appear in your inbox folder. Some of other mailservers out there like Facebook, Yahoo, Gmail and etc will assume the email sent by this system are spams. Why? I even can’t explain it. Well at least the email were sent and received.
