I think he should make a decent post about his site first. Creating a detailed ANN thread is better so it won't create confusion for those who want to explore it. If it's still under development, they should polish it first before asking the players to try out their casino because it might cause problems in the end which will be unfair to the users.
They did posted an ANN thread for their casino, which can be found
here. However, it appears that they didn't invest much effort into making it engaging and enticing for potential players. That's why I asked him about whether the casino site is still being developed.
I agree that they should finish up the casino site before promoting it. It just makes more sense.
