Advanced login system - repost

I need an advanced login system with: Admin Cpanel Registeration Forgot Password Account activation Number of registered Members Number of Online Users Password Change BBcoin Balance (BlackBone coin) (it\'s like a normal balance but the difference the currency is BBcoin) Auto Checkout for BBcoins (Automatically add number of BBcoins Purchased) 1 USD = 1 BBcoin Send BBcoins to other members Send Private messages to users now listen, here\'s the big catch, im going to sell prepaid cards but the difference the customers will pay 90% of it, and pick a number and then I go to [login to view URL] and the website will generate a number! so can you make a script for this? like I need to know who picked that number only and then I send him the prepaid card manually...
