By communicating with community can make a good interaction can increase their relationship to better so they can feels closer to the casino. That will help the community to knows more about the casino so they can choose the casino as a place to gambling. Community will gives their suggestion if they see something needs to be added to the casino.
That will help casino to develops more and gives the best services to their community. It is not easy because that needs an effort to always hear what community say. But a serious casino will do that because they want to satisfy all people who visits their casino.
That is why casino needs to have a strong solid team so they can work good and make sure that they serves their members. When they can satisfy their members, that will be a way to grows their business.
Well, how can you disagree? You are right. If something should happen, it should be some privileges for regular players. For example, it could be some bonus points and/or money to the account. A new casino should conduct such a practice constantly. It will attract much more attention than other promotion methods. It is enough to follow the example of others and everything will become crystal clear.
If I were the admin, I would organize a permanent contest with prizes on the forum, which will increase audience involvement. Every week conduct a survey on some sports topic or something similar.
