* While in test mode, I'd generate bitcoin testnet addresses to prevent people from accidentally depositing. (In fact, if you wanted you could test the deposit and withdrawal system by supporting testcoins).
I'd do this too but I didn't want to download the blockchain for testnet.
* You should probably get a .com domain, even if the domain is a bit worse. That way the ".net" doesn't need to be part of your brand
You are right, I've registered a .com domain too. Also I added confirm() and font issue to todo list. Thanks for your kind words and support.
I noticed that as test accounts lose their credits their balance is added to the 'available to win' pot. When you stop testing will that balance be reset to real bits only? If not it'd be a bit dishonest, making people think there is a much higher reward available than what is truly there.
I'll reset the database data when site goes live. It's currently not in production stage.
