The offer is still currently available and will available for another few days. You can order today and your account will be setup automatically, the coupon will last one month so you will get a month free. So after your exam is over you can continue using your 3 months worth of your free web hosting.
Can any one make me convince that it's not going to be another STABLELAYER ???
I'm not. I just respect wJunction and it's members and I hope that people will respect the coupon code. It will expire shortly. We actually have a limit on the amount of account we put on our servers. That limit depends on how much resources each site consumes and for how long.
