Players who play online must obey various rules of etiquette just as they do if they play in a brick and mortar casino. These mostly apply to play in the chat room. Players never want to be abusive when they are online.
The chat room moderator can block players who are abusive. Players play online in the chat room because they want to have a good time and having a good time does not mean putting up with someone else's abuse. Players who have had a bad day or who are losing should not take it out on the chat room staff.
It is not the moderator's fault that the player is losing and the other players don't want to hear about it. Remember there are always opportunities to play games such as Rainbow Riches for free online. Players should obey the rules of the chat which they will find published somewhere on the website. This will mean eventually learning the chat room lingo.
These are just the abbreviations used in the chat room so that players don't have to type out long sentences and words. Players new to the chat room should let the other know that they are new and they will help them with the lingo. Don't try to hog the chat room facility since it is there for the use of all players, not just a select few. Be sure to let others have their say. The best rule is to treat others as you yourself would wish to be treated. That is always one of the best rules to follow.
