Well if he doesn't it will be a repeat of last time, so called great coders of the habbo sections will 'code' a habbo cms and most of the time it will completely fail (Thats not to say there's not some excellent coders out there i.e. Rasta, Kryptos ;D, Privilege etc..)
Noone will pay for these, for one thing, it's just a bunch of images copied and pated then made to flash or move which is pretty simple to do and many people who are genrous will do it for free if you ask, if they were more detailed and the background images had been created from scratch then...
I normally use CMD with the command 'netstat -n' to get the ddoser IP then block the IP with Peerblock which blocks it on all ports, not just 80 (if you used htaccess)
Do that in here; C:\Users\Danielle\Downloads\xampp\htdocs\core.php
or I'd probably take Kierans advice which is probably easier and get another copy of phpretro;

I think you just screenshot funny chats you've had on omegle.com and upload them here for others to see them and vote them up. If I'm correct I think it'll be an excellent webste and I'm looking forward to seeing it in action ;)
